42lb injectors/2.7 pulley?
Reading a lot of posts on here about 42lb injectors not working with pulley smaller than 2.8 why. Also bought the stage III kit from cobalt addiction if this is a bad combination why would they sell it that way?

thanks for the info in advance

when you say proper octane you mean 93 it would it have to be higher

When your forcing that much air into the motor the injectors can't deliver enough fuel to keep a safe air to fuel ratio...... Boom . Thats my understanding anyways , i could be wrong .

Me 2, I just ran on the Dyno with 42.5 & a 2.8 with 244 hp & 231 wtq, Sounds like you got a really bad tune!
My A/F mixture on 3 runs was 11.60, 11.44, 11.40
My timing advancement is 16.5
0 KR
IAT's were 90 degress & temp outside was 87

My tune is very conservative!
