I have a 2006 GT 5-spd with a borla axle back, JLT CAI, and an Edelbrock nitrous kit. I'm going to be adding a set of Brenspeed Detroit Rockers or FRPP Hot Rod cams and the steeda charge motion plates. I talked to American Muscle and they said that if I backed the nitrous jetting down to 100 and did the FRPP cams, they could email me a tune, I think it's $50, so $100 total, one for nitrous, one without. Brenspeed said that I could go with their cams and keep a 125 shot and they could email me a tune for $185 that includes one for nitrous, one without. One, which cam would be the better choice. They seem to have similar power gains, but I want a nice lopey cam. Second, how much power and MPG will I lose if I daily drive the car on the nitrous tune? And lastly, this is SO much cheaper than getting it dyno tuned. Will I be at risk of blowing my motor? Or are these email tunes reliable? Thanks!!! (Sorry about the long post lol lots of questions)
