I'd go with Reptile since he's on the forum. He did one for me (which I haven't installed yet) and he's always responded really fast with any questions I've had.

He has an 04+.

Will does bump up the line pressure.. And remember is a GXP I don't think Reptile does the LS platform

Ah, my bad.

Confirmed though, He doesn't do GXP. DHP won't support it.

He has an 04+.

I'm working on it though, I swear.

 

[Booba5185]

He also has a GXP.

I know, I was just being general on the 04+

Oh OK, no LS stuff in the future, right? I have a buddy with a GXP

Nope....after Blueguy's GXP, I'm not gonna touch them with a 10 foot pole. LOL

Lol

Ls **** is so easy though. If you want I can shoot my trans settings out to whoever needs them

DHP doesn't read GXPs thought, right?

 

[91parkave]

Nope

So I installed the Overkill PCM and TCM couple days ago and it definitely firmed up the shifts. Everything was great until today driving and from a dead stop it did the delayed engagement thing again. I took off and it banged into gear. I made a discovery however. When it is doing delayed engagement.What its actually doing is taking off or trying to take off in 2nd and then slamming back into 1st. I pulled the shifter back to TAPShift and saw that it was showing "2" on the display when taking off from a dead stop. What is causing the transmission to do this!?
