full E85 = 100%..... no mixes

ZZP cams with the upgraded fuel lobe is all you need to run full E85 and actually benefit from it.

all you want is 300hp? that's easy. find a good tuner who uses HPTuners and you'll be set. a friend of mine hooked me up a while back with his winter tune from his Cobalt SS Turbo, it put down 300whp/362wtq on a DynoJet, that tune was VERY FUN. then i stupidily went to a 30psi tune and well.... i don't like talking about what happened.

over spinning the turbo, created a lot of hot boosted air, 2 pistons committed suicide.

if i was running meth injection, it would've been fine because of the additional cooling/fueling it provides.

just wasn't worth it on the stock turbo.

i am near the great lakes and have the stage 1 kit no tune other than that the most i can hit is 19 psi although today is very humid. As well just put in new cam actuators. The most I can remember is getting 20 to 21 which is what most have said is normal.
