Damn!!! It's amazing that it actually pulls longer on more boost... weird. What is causing it to drop off on the lower setting?

If I had to guess, at only 7.5psi that turbo isn't even close to running near its max efficiency. Looks like a decently healthy cam too. Looks to me like there is still a few more pounds left in it before it starts dropping off again.

Those Precision turbos always seem to make great power.

The 30 gph meth I was shooting was killing the low setting. Hard to tune on the street beacause it blows the tires off so quick. log shows single digit afr on that low pull. STOCK intake TB fuel rails regulator and lines FTW

stock lines will make well more since you are on gas. I'm pushing similar on straight e85. stock lines and filter.

I'd be curious what it would run in the 1/4 on the 17 psi setting

Low to mid 10's would be my guess.

Looks like it runs real well. Probably stand to pick up some substantial power by picking the timing up if the fueling is right, especially after peak torque. This is my setup a couple years ago, very similar to yours. Only difference is I had the triple 12 and was running e43, no meth, 17psi. IIRC it made 540hp on 5-6psi. Cool to see how the cams compare.
