So I need to throw a question out there. I just completed a build on my '91 GTi-R, and just heard from the tuner. My power numbers are drastically different from the results of others/Fusion Motorsport guide. I'll start with the build specs.
-Walbro 255lph pump
-Deatschwerks 1050 injectors
-NISMO fuel press. reg.
-AMPerformance 3" full exhaust
-Garrett GTX2871R turbo
-Innovate Motorsports PSB-1
-Linq Standalone ECU
If I think of anything further I will add, but this is all that comes to memory...
Was just told by the tuner it made 271hp and 254ft/lbs @ approx. 18psi boost, 92 octane at the wheels. They ran into fueling problems (i.e. detonation) when pushed any further.
These numbers are drastically different than other builds I've seen (Fusion, forum builds, etc...). Is it because my numbers are at the wheels? I know the TMIC will cause higher intake temps, but i was still expecting 350 ish...
If anyone can help me understand this it would be greatly appreciated.
