i just got my thumpr stage 2 cams installed and it sounds freaking awesome, but the car isn;t running quite right. it feels flat at about 1500 to 3500 rpm's and it hesitates and pops. 4th and 5th gear feel like they have no power what so ever. sorry to rample on i guess what i am getting at is how many tunes did it take to get it right with other peoples cam installs? everyones oppinion is appreciated. oh and by the way i did get my tune from a reputable tuner and they are working with me.
