Dumb Question
I have twins on my c5. Puttin down about 800-850. I am doing this thru stock ls6 manifold . question is if i get a tpis conversion to a 90mm tb how much gain can i expect. running around 15 lbs now. i feel my tb and perhaps intercoolers are the new bottlenecks.

I would be more concenrd about the possible leaks from the epoxy job, if you absolutely need a 90mm tb then maybe get an ls2 intake
