Got my car tuned but its going back soon.

Anyway its an R33 GTST Series 2 with the following:

Unopened RB25DET

HyperGear ATR43SS-2

3" JJR Bellmouth dump

HKS Hi Power Silent exhaust

Yellow jacket coils

NGK Copper plugs BCP7RES gapped to .7

Genuine HDI FMIC

Venom 5" body 100cpsi cat

Nismo 740cc injectors

Bosch 040(was failing during tune)

Nismo FPR

Greddy profec b spec 2

3" metal intake with Apexi power intake filter

Power FC tuned by Advan performance

Made 244rwkw on 11.4psi. That is with the boost controller set to 100%. That is as much as we can get out of it. With about 15psi, we should see about 270rwkw and 17psi about 280rwkw. 20psi should see 300rwkw on regular fuel pump.

Ive fitted a GTR fuel pump in there to fix the fuel pump issues. Probably will swap that with a brand new 040 pump or run it as a lift into a surge tank. Last printed dyno shows about 238rwkw on 11psi, should have printed the previous runs :P

Got it retuned, the AFR is perfect. Running more boost 15 low 19 high. Oddly enough high boost is seeing 250rwkw low boost is on about 217rwkw but low boost feels much stronger than the original 244rwkw on 11psi... Mind boggling. Intake pipe might be a huge restriction. Making close to 700nm of torque, it absolutely rips my face off compared to what it was before. Very impressed with the thorough tuning work done by Jez and bordy. A dyno gives you a number, but what you feel on the road is what counts and wow this is amazing. Just driving home on low boost the lift on the front end was intense.

    • I'll bite. I no longer own any euro's, but I thought I'd share two of my favorites I owned. My 500hp B5 S4 and my 800HP E55 AMG. Yes I did attempt to drive the E55 in Canadian winters, that lasted all of a month as it was a death trap.   
    • To be fair this is the wife’s car. However, I have been accused of owning more cars than I have pairs of undies. Luckily I change my undies more frequently than the cars.
    • Cheers Lads Looking at changing up a few things maybe go 2.8lt, bigger injectors with more a modern Turbo. Possibly transbrake and convert to E85 with Haltech ECU. Any thoughts on those Mods changes or better ideas? Want to try keep the car Street/Strip While also being weekend drivable still.
