After a couple months Building my rear-mount system truck only made 300 hp and 350 tq. Its a 06 5.3 rcsb. Turbo Im running is a 67mm comp technology with .81 ar. Its the oil-less turbo that cools of the engine's coolant. Have a non turbo friendly cam 112 lsa. longtube headers which im going going to switch back to manifolds. Have precision wastegate with 9.4 spring right now. Truck is barely pulling 6 pounds and takes forever to spool to that. Hopefully after wrapping my manifolds and exhaust It will spool better. I also Have the wastegate hooked directly to the turbo which I will be changing. Little disapointed but at least its a start and I can drive the truck now.

 

Are the hot pipes wrapped? I woulda thought it would make more power.

who tuned it?

 

need to switch back to stock manifolds and smaller dia. exhaust

 

No the hot pipes were not wrapped yet. And I will be switching back to manifolds and smaller y-pipe

 

When I had my sts setup, I had headers on it. Just from switch back to the stock manifolds it was a huge difference.

 

Your charge pipe from the turbo back up front should be 2.5 in too

Wrap the stock manifolds and all the hot pipes and leave everything else the same then get back to us.

 

Yes, my cold side is all 2.5 with a large intercooler. I should be able to have it back to the dyno in a week with the manifolds wrapped. I was also told I was around 12 degrees timing.

 

you don't or wont need to wrap your manifolds just the piping to the turbo

 

Is wrapping the hotpipes really that beneficial? I dont have mine wrapped, and have been wondering how much of a difference it would make. I can tell a big difference in spool time when the pipes are hot versus when they are cold.

 

There is a huge difference between wrapped hot pipes and not. Mine are double wrapped all the way back and the turbo has no trouble spooling.
