Other thread said 18.5 to 19 PSI boost, but was not sure if that was a spike or not. My spikes on meth are 16.7 - 16.9 while the normal boost is 16.5 (In manifold). That's 93 octane on 80/20 meth with DO7 nozzle. The OP was running M8 nozzle with 100% home depot, denatured alcohol and a mix of 92 and 94 octane. Meth starts to spray at 7PSI (i start at the same boost).

Very nice numbers, however, I'm not sure i'd want that much more torque than hp. I'd actually rather the numbers be twitched. Thank goodness for traction control, otherwise your tires would be gone.

FWIW, 483 lbs. torque @ 16 psi boost is unusually high for a 3.0 L engine. The 431 HP is about right. There could be boost over-shoot producing the higher than normal torque?

If however you really have 4083 lbs. of torque then you're running more like 340 psi boost.

This isn't 16psi, it's 16 deg timing..this was 18-20psi max boost

I too am intersted too see the diff with the AR pipes. You are probably going to squeeze a couple more HP out of them would be my guess.

Ya, post up your map 1 settings, would love to see them.

These are the settings of one of my better pulls. I forgot to save my logs during a few runs. I know i started at hp 96 and torque 96. I went up every pull. My highest boost was 18.5psi.

M1Power 97

looking at your dyno graph i wouldn't dare launch that car in between 3k and 5.5k RPM...otherwise, halfshaft bye-bye...i'd probably try to launch above 6k rpm on DRs or 2.5k...maybe try raising your suspension a bit to save those CV joints...you running coils or just springs?

FYI, most I tried when I was trying jb3 2.0 with full catless boltons was:

Torque 84
HP 55
IAT 8
Fuel 100
Lagfix 100
Boost Limit 17.5

With your settings I think you were boost targeting close to 20psi or maybe more...i do that only on race+meth only at the 1/4 though...

He was on 93 octane pump gas.. Had his old UR Dp's on inside of the new Ar dp's. With racegas and the new DP's he can custom tune even more to get more power with the race gas.
