i was just wonderin if an lt1 can get to much air cause i raced a friend(00' ws6 full bolt on) before i made my high flow lid from a dig and i beat him by a good 4-5 lengths and from a roll it would be about even,and i raced him after the new lid and he beat me by about 1 1/2-2 lengths from a dig but i beat him from a roll ,i also noticed when we went from a dig that my car was kinda lagging from 2500-4500rpm and then it would come alive,but when we went from a roll i was already @ about 4500 when we took off so it didnt lag and i would put multiple lengths on him,anybody ever had this problem after changing a cai?if anybody could throw me some suggestions i'd really appreciate it!

Do you have any form of wideband o2 sensor? I bet you changed so much with the lid that it has thrown your tune off down low. I would check into getting a good wideband (if you don't have one) with a good gauge (not that light show autometer one) and then investing in a data cable for a laptop. Download the tuner cats software and start learning. I bet you will be pleastantly surprised how much you can gain over your mail order tune if you can get it just right.

yeah thats pretty much what i was thinking,is tunercat real complicated or is it relatively easy to use?

Its complicated. Take your time and read as much as you can and it won't be terrible.
