I made 200rwhp with them. 6:1 rise, 11psi, stock AFM, Bipes for timing.

Probably could have gone to 4:1; rich as hell past 5.5K

12psi of boost
90psi of fuel pressure
Base timing 14* w/Bipes pulling 7*
OG's 02Clamp at stock setting

Here's my curves. You can see my progression. First two runs I was running way too much fuel... next 5runs after I pulled about 20psi of fuel pressure and expirimented w/2xCheckValves on the AFPR to lean it out a little more up top. It was a wash cause it leaned it out a little too much in the midrange. I really wanted to play with the 02Clamp voltage and lean it out a little more down low... but I was so happy with how easy the rest of it was that I didn't care. It's retty much as good as it's going to get w/SR20T25 and full bandaids. Leans out into the low 13's in midrange and low 11's up top. My last runs in GREEN were back-to-back after the others and I'm sure everything was heat soaked... it knocked and I cut the run short. I pulled another 1* on the Bipes and have run it just like that since then w/no knock ever even in the 100* Virginia summer. It had peaked in TQ, but you can see the HP curve is still screaming up... I'm confident it makes over 200whp/190tq on the street.
