Full Bolt on dyno #'s

Just got the car dyno tuned yesterday and am very pleased with the results. This was the car's first time ever on a dyno so I wish I had some before and after #'s for you guys. SAE corrected I made 356hp and 369tq. Hp is about where I thought it would be but the tq # to me is simply amazing. Peak tq came at 4300 with the hp peaking at 5400. Mods are in the sig and this was done with cats and through a hooker catback. I really think my tq numbers are a testament to the quality of the merges on the Amarican Racing headers and y pipe.

Thanks man. Im really pumped about how the car runs now. This was on a dynojet. Temp was 82, humidity was 85%, pressure was 29.51. It was a very muggy and humid day. SAE J1349 correction factor was 1.06. The car is so much more fun to drive now that the tune is done. I would reccomend it to anybody who is full bolt on.

Stout numbers and +1 on the tune. My tune made a world of difference. I need to dyno mine and see what she does.

On a dynapack I made 364.1 RWHP as a baseline run and 341 RWTQ

I think these numbers are a little high for just boltons.

im not sure about the hp, but anything can happen. i made 352/360 thru my stock catback with just lid and longtubes.... and mine is a 99 with the ls1 intake. when i put the 12 bolt and 3.73 gears in, i made 344/356.... but i had dual cutouts this time. with the cutouts closed i dropped to 330/348.
