Default Before and after QTP longtubes

My base line was with a Whisper lid, Magnaflow catback. Can't remember if I had descreen the maf. Final numbers do include throttlebody bypass, descreened maf. They added some fuel up top as it was leaning out. Looking forward to LS6 intake, ported TB, and UDP. 3.42 gears until I get the money for a 9". For whatever reason, my printed copy shows 332/341 max.

No, I do believe another issue is my Y. It's a pacesetter cut up several places and rewelded to fit up. Later down the road I plan to buy whatever Y that works properly or possibly true duals. You don't know how bad it kills me to drive around with 3.42's, but I figured the $500 or so it costs to have 4.10's installed is better applied towards a 9" rear.

i'm in the same boat as you but i think with my mods the 10 bolt should hold up and i don't plan on doing anything for a while after the 4.10s. i don't go to the track either so my car stays on street tires.
