Well I had gone to the track a couple weeks ago and was very very dissapointed with the gains I got from the new opti and coil. The car felt so much better yet I had very wierd results at the track. Keep in mind this is not a proffesional track and I am at 4000+ elevation. Stock Lt1's run mid 15's. Oh and the mph is not correct, the tracks mph is about 4 to 5 mph to slow so add 5 to the given ones below.

Before opti & Coil: 14.7@94.5mph steady.

After opti& coil: 14.5 @92mph steady.

So I was unable to figure out why I was getting strange results. Off the line I MURDER people, then my top end lets off pretty good. So I ordered an Lt4 Knock Module and low and behold once it is in my car is running like an aggresive champ waiting to pounce. I do not have headers but have a cat-back and the mods in sig.... The car was obviously retarting timing really baddly because now it no longer lets off in the top end. I have pcmforless and wonder if this could have been a possible culprit..???

What do you all think....the car just has more power now period????
