+1 My comment was not meant towards an insult at all-both to you or your shop/tuner. I have cams, I guess your running stock cams, that def makes a difference. But look around to MRC/GTM/Forged they dont generally run more than 15/16psi on pump-its for a reason Regardless, your car makes good power and your happy with it. Thanks for the comparison...

Quick correction.
DD read within 1% repeatibility worldwide, it's kind of our standard. The DJ's are the ones w/ the variance in power readings. It's a pretty simple test, just run on a couple different DJs and see the numbers bounce around. Run on different DDs in shootout mode and all the numbers will be right on top of each other.

I totally agree with you. I typically tell customers to run at least a 50/50 mix of 100/93 octane for 18psi maps. Bulletproof is a well informed guy. His G has become a "shop car". We have very refined numbers in his UTEC. He's the type of customer that really listens to recommendations. There's no point for the 18psi map around town anyway...unless you like buying really expensive 19" bridgestones

I know you werent knocking my tuner, i was joking. I have scotts performance cams in the car. but with your compression ratio higher than mine, i expected you to make more power than me.

DAMN TWIN CARBON! All other things being equal, I think you would have had even slightly higher numbers with a few more pulls. That clutch needs heat to get it holding properly.

Not neccessarily true! Ive seen 8.5:1 cars at Forged make more power than me (at same boost-simialr set-ups) due to Sharif being able to run slightly more aggressive timing over my set-up. Every car is different, you cant speculate that a higher comp = more power.

underpressure-good info
