Justin brought us his SUPER clean Z32 over the weekend for a tune.

Here is the setup:

Stock VG30DETT
Stock Turbos

740cc Injectors
Walbro 255 LPH Fuel Pump

Dual N62 MAFs
Twin Intakes
Selin Device (MAF Translator)
ASH Spec Intercoolers
Apexi Exhaust
Apexi Downpipes

Tuned on Nistune
(previously on a ROM tune)

Justin's car was tuned with the fans off, with multiple back to back pulls, to simulate a heat soak condition. The red chart is the base pull, and the blue chart is our tune.

Thats some good power! What is the redline? It looks like those stock turbos are still flowing pretty good up top!

The turbos have internal wastegates so it would hit 17.5psi at 65mph and come down to 13.5-14psi almost immediately despite the EBC doing it's best. This is somewhat typical on these setups with internal wastegates, otherwise I'm pretty confident it would of seen low 400's.

As posted by the customer, and yes, it's correct:

Peak Torque was ~420 @ 4500rpm

here is the logic:

Tire Width in (mm): 265
Aspect Ratio: 35
Rim Diameter in (inch): 18
Transmission Gear Ratio: 1.302
Differential Ratio (final drive): 4.08

Transmission Gearing:
1st 3.214
2nd 1.925
3rd 1.302 <-- based off what I see, pulls were done in 3rd gear
4th 1.000
5th 0.752

Formula for Horsepower:
(Torque x RPM) / 5252 = Horsepower
