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.
Airbox for Jenvey VQ35 ITB Kit
A new airbox for the VQ35 Individual Throttle Body kit was released this weekend at the PRI Performance Racing show in Orlando, FL. Final tweaking is still required to ensure a proper fit under the 350Z and G35 hood, but here is the closest thing they have to production. A few photos from Jenvey’s ITB booth at the show:
Individual Throttle Bodies for VQ35DE
Today we received the first set of Jenvey Individual Throttle Bodies for the VQ35DE to be installed on a customer’s stroked motor. These are now for sale on our 350ZMod store!
