Well I got my truck back from the trans shop yesterday and while it was there I changed out the wastegate to a new one sent by STS, and also changed the PCM to a new one programmed by Allen at Nelson performance.
The shop worked with Allen on the programming requirements so it seems to shift allot better than the first PCM I got. I am now on my 4th PCM and counting. The truck so far works pretty well, I'll be testing it ouit for the next couple of days and give a report. The turbo is no longer overboosting by 5psi, and the trans feels strong and tight. I have been reasured by my trans guy that I should have no future problems even if I go up to 7psi or so.
The thing chips the tires at part throttle and burns the peg legger at 30 mph after downshifting!! I can't wait for the posi to get this thing hooking up now.
Hopefully all my major problems are in the past. Oh ya I got an 18 month or 18,000 mile warranty which ever comes first.

 

congrats! sounds awesome and warranty can't hurt either!

 

get a posi and crank that boost up.

 

Nice sounds like its coming along pretty well. Now you gotta go play and get some track times

 

Does it have a billet servo?4l60s dont like hard hard shifts.input drums shatter.

 

nice...glad to see you back in your truck and all the issues taken care of

 

Corvette servo installed and some of the parts have been modified. I'm trying to get a complete list and details from my trans guy so I can post em up here.

This is what I have now.
Z-Pack 3-4 clutch, wide 2-4 band, High performance servo and valve body kit and torque converter mods per engine package(STS Turbo).
I also know they split the converter and tack welded all the fins.

 

I built my OE just like how yours is now, along with beast sunshell,29el sprag.superior shift kit,worked perfect with the vette servo.I then went against what I have always preached,dont run billet servos with much pressure seems it was almost a year and hard use.One day 1/2 throttle 1-2 shift BANG i know exactly what it did.Thats what happends when you dont practice what you preach.I slapped in a new 4mi take out 03 Denali 4l65e,had my converter cut opened and cleaned vette servo and recently did a HD transgo.the 1-2 is a touch to hard at mid throttle,I need to change my PCM pressures.

 

yeah im going to be taking out my billet (super) servo, the 1-2 chirp is get annoying.

 

I may buy a new seperator plate and redrill it and drill the 1-2 feed on the mild side of the SK instructions.
