conservative tuning for pump fuel :lol

and yes, find the point of knock, and back it off until it stops. not a hard concept to follow.

im not a huge meth fan, sure i could use it, run my race map all day long, but i just dont want to risk of that pump failing on me. sure my fuel pump coudl die and do just as much damage. but i wouldnt feel as bad.

people always say they just want meth for the cooling properties, and " im not going to tune for it, no added timing" and what happens? they throw a ton of timing towards it and have a 93+ meth tune on the car. then the pump fails. i know this why?? we did that to alot of evos, and what happened?? snow performance pump failed, and the “fail safe” failed as well :banghead

^ car was my roomates FP green evo 8. the pump failed at a 75/25% mix, whatever happened, who knows, lucked out, and only lifted the head, nothing melted… it was approx a 10% fail rate for us, but still, enough to scare me away
