I HAVE A 97 Z, WITH 113,000 MILE ON IT. I BOUGHT IT TO HAVE AS AN EVERYDAY DRIVER AND THE ONLY THINGS IT HAD DONE TO IT WHEN I GOT IT WAS COLD AIR AND BORLA CAT-BACK. I NEED A TUNE UP SO MY PLAN WAS TO PUT THE LT'S ON SINCE IM GOING TO HAVE THE MANIFOLDS OFF ANY WAY. SO THE QUESTION IS HOW MUCH HP WILL I GAIN?


THANX FOR THE ADVICE.

97' Z28, ANN. COLD AIR, CAT-BACK, HYPERTECH AND 373'S

 

10-20 would be my estimate

 

Welcome to the board man. I am not trying to be a pain-in-the-@@s, but general questions like that one, using the search button is very useful. That topic is discussed a LOT and you will find tons of info using a search. Take care.

 

SORRY FOR BEING THE NEW JACK===. ILL TRY THE SEARCH NEXT TIME

 

Like I said, no offense.
