GXP LT dyno numbers??

[Oxygen]

I know a few guys have installed LT's on their GXP's. What happened to the dyno reports after the iinstall??

I am thinking maybe the improvement isn't as much as on the GT??

I didn't have time to get it dyno'd after my install. I will get it dyno'd in a couple of weeks though. The gains probably won't be as much because the GXP exhaust is less restrictive than the GT. We'll see though...

Curious as well.....I might even venture off to say it'll be close to the GT's gains.

I think you are correct.

bet the opposite, bigger gains on the GXP then on the GT. same basic manifolds, and exhaust, but the ls3 is a much stouter engine than the l92. i would use 1 3/4 headers unless going with FI or nitrous. tried the 1 7/8 on my CTS v and lost a lot of TQ compared to gaining 3 hp way up top.

Please note in posting if using 1 7/8" or 1 3/4" primary tubes on your LT's.

I would expect the GXP to make make more just based on the gains the LS3 vettes get with them.

Can't wait to do mine...soooon very soon.
