I know this plot is going to look different to most. This tune and plot was solely for NASA TT4 time trials competition where you have to set a competition awhp number and weight. TT4 is 12:1 weight : power ratio. My goal was to get the flattest hp curve I could get with a max of 284 awhp. Here are the relevant mods:

Evo 9 Ported Turbo
Forced Performance Cast Ported Turbo Manifold
Port Matched Intake Manifold
ETS 3" Intercooler
AMS Upper Intercooler Pipe
CBRD Lower Intercooler Pipe
TiAL Q BOV
Injector Dynamics 1300cc Injectors
Walbro 450 Fuel Pump (Dual Voltage)
Schmuck Built Intake with Perrin Filter
Turbo XS 3" Turbo Back Exhaust
Perrin Pro Electronic Boost Control Solenoid
Tephra v7 Speed Density Tuned

I had them start the pull at 4000 RPM because all I cared about was making sure the car was NASA TT4 legal. The dyno also had lots of issues with keeping a good reliable tach signal throughout the runs. We did 6 runs and these were the 3 best, and you can still see that the blue one had a few bad RPM values and the green one had a phantom one at 9000 RPM that caused it to not look like we hit the rev limiter. Here is the plot:
