OK Zenkat and TunerLover --- here's the update as of today after I took the car into the shop and played with the DSP and simultaneously had it hooked up to the dyno.
Just to refresh, here's what the car has on it today (so still fairly stock):
CAI, mopar/borla catback exhaust, mopar stage 1 PCM, Hondata intake manifold gasket, Granatelli wires and NGK Iridium plugs, stock WGA (I took the AGP WGA off), and MPX 62mm TB. As far as I can tell, I have all the vacuum lines hooked up correctly, and I put new T-bolt clamps on the cold side pipes of the intercooler and double-check tightness on the other IC inlet hose fittings.
We installed the 93 oct. tune with the DSP, but it was horsepower and torque curves were peaky (not smooth), so we decided to do a custom tune which produced a much smoother, increasing set of curves, reaching peak torque (262 ft-lbs at wheels at 4250 rpm) and peak hp (240 hp at wheels at 5250 rpm).
These numbers seem OK but maybe a bit low?? What has me puzzled though is that the boost peaked at 16 psi at 2800 rpm, held fairly steady at around 15 psi up to 4800 rpm, and fell down to 13-14 psi towards redline.
So here are my questions (sorry for being so long winded):
1) We had programmed the max. boost within each of the 1000 rpm increments (e.g., 3000-4000 rpm, 4000-5000 rpm, 5000-6000 rpm) to peak at 25 psi. So why aren't I getting more boost?? Is it a boost leak, or will the stock WGA not allow this much boost??
2) Is the MPX TB still screwing things up?? I regret buying it now.
3) I had the Iridiums gapped to .038" (this is what I read on Forum a while back). But the tuner mechanic said that's way too much and said they should be gapped to .028". Which gap is correct??
THANKS AGAIN for your help on this guys!!
