I was wondering how much slower my truck would be if I put a 6inch lift with 35"s on it? I have a 06 lbz with PPE excelleratoron level three and 5inch turbo back. If I lifted it would right off the bat I notice it being slower compared to when it was lower? I want to build my trans and go up to hot plus 2 but I also want to get a lift. Do you think that it is a good idea to put a lift on a truck with that much horsepower or should I decide on one or the other? Does lifting it defeat the purpose of the chip? Sorry for all the questions I was just wondering what you guys think I should do.
Thanks Matt

Lift = more weight, more wind resistance and more rolling resistance from the larger tires. You will notice a difference in handling and performance.

A lot hinges on what you are expecting from your truck.

how quick are you wanting it i can still out run my bosses mustang and i have 37" and 4.56 gears. when i did my lift i noticed some difference but the benefits of the lift out weighted the performance lose i could notice which wasn't much

You wont notice much of a difference performance wise, but you will notice a little, mine was lifted on 38's and still took off like a bat out of hell!
