[QUOTE="Tranzlucent, post: 2750000, member: 13046"] If you are running 75-150hp on an already FI motor with no tune, you have a timebomb. I hope that no one is paying you to work on their cars. Yeah you might check an a/f ratio here or there, but what happens when it gets colder/warmer. Things do change. The other think you just stated you think the rear will hold from a roll? Even with drag radials, you can experience severe spin from a 40-50mph with enough power. You also run into issues with twisting the input shaft on the tranny with enough power. Plenty of people have done that. Also if you do stick it from 40-50, you still put tremendous pressure on our weak rear differentials. You just might be the Cobra noob you alluded to earlier. NO ONE, THAT'S RIGHT, NO ONE would consider running 75-150 shot untuned on these cars. I'll give you that the stock tune might be rich, but it has several spikes in it and goes lean from here to there. [/QUOTE]
