A Quick Tour of the New Shop
Did you know that we’ve recently expanded? Over the winter, significant time and effort was invested in order to grow our shop facility. This additional work area can accommodate for up to five cars being worked on at a time, as well as safe, secure overnight storage for seven cars each night.
Paired with a staggering array of tools, this additional work space provides the well-lit and spacious atmosphere to make sure that every job is handled appropriately. Two additional new lifts complement the existing two lifts in the original warehouse, which also houses our Dyno Dynamics dyno. A clean engine room serves as the environment for assembling the highest horsepower VQ engines in the world, as well as any other specialty projects involving exact measurement. Finally, a sealed fabrication room is available for those unique jobs and to ensure that byproducts of welding and cutting do not find their way into the work area.
With that said, our entire facility consists of:
- Over 10,000 square feet of office space, inventory warehousing, and shop working space
- Four hydraulic lifts to accommodate for the lowest of vehicles
- Dyno Dynamics two wheel drive dyno and engine tuning
- Welding and fabrication tools and abilities
- Precision engine assembly tools and abilities
- Hunter mounting and balancing equipment
- Almost any other tool you can possibly imagine
- Racing fuel inventory and nitrous re-filling
- Convenient location in downtown Lexington, KY
Current labor rates for 2010 are as follows:
- Standard labor rate: $90 per hour
- Dyno tuning rate: $170 per hour
With this additional facility, we welcome jobs both large and small! Please contact us via email for a thorough price quote and schedule request. As a reminder, we still pride ourselves in low prices and quick turnaround time for parts sales, so give us a try for your one-stop source.

E85 Tuning on GTM Twin Turbo G35
As a repeat customer, we last saw this beautiful example of a street G35 about a year ago. At the time, he brought his built 3.5L VQ35 for a tune on his APS twin turbo kit. Over 500 whp was safely achieved, and the customer backed it up with several 11 second quarter mile passes. While the power level was certainly enjoyable, he craved more. This year, he returned with a new turbo kit, the GTM Stage 5 with twin GT30’s, a bigger fuel system, the CJ Motorsports twin pump hanger and 1200cc injectors, and 30 gallons of E85 gas fresh from the pump.
After battling a smoking problem with the turbo’s oil supply and some electrical problems, we were able to begin tuning. With Hal behind the keyboard, it did not take long to get starting and driveability cleaned up and move on to the power tuning. After a solid baseline tune was established on wastegate spring pressure, 13 psi, the Haltech boost control was enabled and a maximum of 630 whp was achieved before running out of injector duty cycle. It is true that E85 requires as much as 30-40% more fuel compared to gasoline, which is an important factor to consider when weighing alternative options to race gas. Our customer picked up his car and immediately headed down to a National Mustang meet to represent the Nissans.
Since being tuned, this G35 has run an impressive 11.0 at 134 mph in the quarter mile. Judging from the trap speed, we agree that this car has a quicker time in store, even at the same power level. With some upgraded axles and possibly race gas, we look forward to seeing this car running easily in the 10-second range!
Turbonetics Low vs High Boost
Vince’s car made for an interesting case study on the effects of higher boost on some twin turbo kits for the VQ35. This customer had decided to upgrade his injectors to the Deatschwerks drop-in 600cc’s before his tuning session. As a stocking dealer for Deatschwerks, and other injectors, this was not a problem to complete the install and immediately begin the tuning.
After reaching sufficient gains at his current 8 psi, he requested us to turn up the boost to see if more power could be made. While a bit more torque was made throughout the powerband, this dyno shows that a 3 psi gain in boost resulted in more power earlier, but a significant drop off in top-end power. The Turbonetics kit has been known for providing a nice power curve in its’ off the shelf configuration, but it begins to choke the power at higher boost. Both maps were included for the customer to decide which he preferred better.
Travel Tuning
When traveling to our shop for a tune is not an option, we fly to our customers. Last week Hal was down in Houston, TX breaking in a new VQ35. Ernie (aka Niceguy on the forums) has been hard at work in the garage, outfitting his G35 coupe with a new built 3.5L vq35de, SFR twin 60-1 turbo kit, plenum spacer, valve-body upgrade, Precision injectors, return fuel system, custom 3″ exhaust, Haltech dual widebands, and of course a Haltech Platinum 350z ems. After break-in tuning and driveability tuning it was time for the fun part - power tuning. The first dyno run was just shy of 400whp and it was not long until we hit his 500whp goal. Impressive horsepower through the Nissan automatic. Due to high intake air temperatures with the SFR intercoolers (160+°F) we decided to stop here and a more efficient intercooler is in the works. With the tune and the dual widebands at work, the owner was impressed that the car ‘truly drives like stock’.
G35 with Powerlab GT35R becomes 400+whp daily driver
A 2006 Infiniti G35 Coupe was dropped off at the Injected Performance bay doors, equipped with a Powerlab GT35R turbo kit, Haltech Platinum 350Z EMS, and Deatschwerks 600cc injectors. The request was simple: check over the power tune and clean up the driving/cruising tune.
The initial dyno tests revealed this was one strong VQ35DE, breaking 440whp as it came to us at 10psi. The 2006 G35 has a Revup VQ35, though the tune had exhaust cam timing disabled. We enabled cam timing, picked up significant midrange power, and fixed the top end loss it had shown on the first dyno pull. At that point, the VQ35DE was outputting over 450whp at 10psi. This car was still running on the stock engine, and needed to stay that way for some time - so the boost was decreased to 8psi, and the tune was softened up. The final outcome was a safe 424whp.
The car came to us overly rich during cruising, which was quickly remedied by a proper tune on our load bearing Dyno Dynamics and followed up by a street test. A wideband air fuel sensor was wired to the Haltech and O2 correction was enabled to ensure things would continue to run in top form. The customer requested the speed limiter be removed, idle decreased (from a previous increase), and CEL removed - simple tasks all handled by the Injected Performance VQ35DE ECU Reflash. After customer pickup, the car made a 5 hour drive home where it reportedly achieved 26-28mpg.
Overall impressions of the Powerlab GT35R turbo kit are positive. It is one fast spooling kit; able to achieve full boost before 2900rpm and still make impressive top end power. Check out the pictures and video below.
Injected Performance is UpRev Pro-Tuner
Injected Performance has been working with UpRev for some time regarding Nissan ECU reflashes and diagnostics. The relationship has finally been made ‘official’ as UpRev now titles us a ProTuner. We have a Dyno Dynamics in house, and are fully qualified to dyno tune your 350Z or G35 via VQ35DE ecu reflash. Please call 859-224-0461 in advance to schedule your 350Z dyno tuning appointment with Hal.
In addition to fuel, ignition and cam timing tuning, a 350Z reflash allows: speed limiter removal, rev limiter increase, idle increase, CEL code disabling, injector scaling and more. Cipher 350Z diagnostic cables are also in stock.
Infiniti G35 + APS Twin Turbos + Stock VQ35DE = 402whp
Over the New Years holiday we opened the doors to a special out-of-town Infiniti owner. After a 600 mile drive on a base map, the car made it to our facility for a tune on the newly installed Haltech Platinum 350Z EMS. The car was outfitted with the new APS Twin Turbo tuner kit for G35 and an APS Tall Boy Intake Plenum. Props to the owner for installing the turbo kit and other mods himself, very nice work! The APS tuner kit comes without fuel and engine management, so the customer installed Deatschwerks 600cc injectors, a Walbro fuel pump, and of course, the Haltech Platinum 350Z plug and play standalone with boost control solenoid.
After a quick change to NGK Iridium 1-step colder spark plugs with proper gap, Hal was able to quickly achieve the goal of ~400whp on our Dyno Dynamics dynamometer at 10psi. As seen in the dyno chart below, the VQ35DE spools the APS twin turbo setup quickly and gives this G35 a nice strong powerband. The G35 produces more than 300ft/lb of torque from 2900rpm to redline.
