I want to know why I dynoed so low. baseline with a flowmaster 40 series put down 284hp and 292tq . after a tune ,e-fan , intake, 160 thermostat .My best pull was 301hp and 314tq. Something is wrong. I feel that I could have gotten them numbers without a tune and just the boltons. It's as if they never tune it. crazy as that sound. your help would greatly be appreciated. cause I'm puzzled. matt said that the 07 have some learning issues. this maybe, not saying matt is wrong. but the low baseline is killing me and the so so jump in numbers , is crazy!
