Estimated Power Gains...

[Tonys99RamAir]

Hey I just ordered my LS6 intake for my 99 bird, and was wondering what type of hp gains I will be looking at? I have a cam, headers, full exhaust with off-road X, lid and LS1 EDIT. The intake goes on thursday and they are gonna re-tune the PCM, but I have no idea what type of numbers I should see. Does anybody have any ideas?--Tony

Do the FRA mod and have the TB ported since you'll have the lid and manifold off anyway. With the cam and headers i'd think you'd see a good gain...i've heard that stock the gain is about 20rwhp, and is great for top end pull. With cam/headers you'll see more...hopefully. Go to the link for the FRA mod if you haven't done it yet...

.595/.601 232/236 duration. Had it installed today, picked up 18 hp and 15 ft lbs. Not to bad, about what I was expecting.--Tony
