Granted 7 lbs is nothing, so doubling that isn’t too bad i guess. Some SRT-4 guys use map clamps (caps voltage that ecu sees to lean out the a/f mix for more power), but with the Mr2 i wonder if the factory fuel system can safely compensate for twice the boost. Running rich on 7lbs is safe, but what will his a/f be at 14psi? Something just doesn’t add up to me. Im going to try this again here friday night at prp for sport compact night at 15psi… I was at 12psi last week… if I can get the 60ft time down better and shift points im at a 13 sec run. --- _[View the full topic](https://forums.speedlife.net/t/burnyds-91-toyota-mr2-turbo/183902)._
