I am really pleased with this car - simply amazing to drive on the road - silky smooth and loads of low end TQ

Its a Stage II car with a header and upipe and a Perrin FMIC - all the mods are listed on the Dyno Sheet

The peak boost was just under 20 psi on 93 octane pump gas

Holy crap. That's a lot of torque! Nice, but I was wondering why there is such a big drop off of hp?

The power drops off up top - IMHO - due to the header and fmic. The stock turbo can only make so much boost and the boost is falling down big time up top.

An RPM dependant EBC such as the AVCR - Eboost2 - or EVC 6 would help reduce that bost tapering significantly

This customers next step is a FP Green - that should be interesting

What do you think the numbers will be with an FP Green?

Can we see the boost and AFR plots?

Graphs are nice and smooth. Looks like a fun car in spite of the loss of torque up top.

Wow, I didn't think headers and fmic would make that much of a diffence. That hp drop is rather large; 50+ drop off.

So what would you recommend/ not recommend on an 07 protune?

Was he on stock fuel pump and stock BCS?
