Heres some quick info.
2001 C5Z06
UPP twin turbo kit
UPP fuel system
ECS small blower cam (was already on the car)
Full 3" exhaust all the way to the LG big 3 catback.
Alky control meth kit

On 8psi it made 627/601
On 10psi it made 684/636

My tuner backed it down and tuned it very conservatively.
Final numbers were 657/637 on basically a pump gas tune. Car is on 93 with meth.

Car runs strong and feels great. 2 issues though. Its been smoking lately from the exhaust. White smoke, not a lot but noticeable when sitting in traffic or making boost. Car only has 24k miles on it.

Other issue is 3.73 gears are driving me crazy. Any idea how to change to 3.42? What do I need? Its an rpm level 4 rearend.

Interested to see what the smoking issue is...
Solid numbers though!
Is this with the 6182Rs?

White smoke is coolant. Trade someone diffs or send it back to rpm.

5871 turbos and why is there coolant getting to the exhaust and how do I stop that?

I would say oil, not coolant. Most comon cause is a restriction in the oil returns causing the oil to back up into the turbos and dump into the exhaust. Also, do you have a hopped up oil pump on there?

Good job on the #'s though, is it fun?
