Lifter Death - Rebuild leads to Tuning query

[Napalm]

In the Engine side I have another thread about my lifter death into engine rework.

09 G8GT - 149K on the clock - engine unmolested - into

DOD delete, LS3 Hot Cam, New parts around - button up and pray.


My main questions to you tuner guys out there:

1)Do any of you happen to have or know of an HP Tuners file set that would work on the LS3/376 crate motors? That is more or less what I'm going to end up with in my car once finished - hopefully.

2) Otherwise does anyone have a 09 GXP automatic base tune that I could download and copy from? As I feel that might well be my best start up option.

3) any suggestions or thoughts of what I should be concerned over. I'm a bit of a noob for tuning and dabbled very little on the g8 when I got it - never really had the time.

OH I have HP Tuners - but need to reload the software and I have the Pro model MVPI device.

Thank you again

Just for the record, you will NOT end up with a 476 CI LS3!

Did you look on the HP Tuners site? Sometimes they have tunes on there.

I said more or less.

I need to look though HP tuners pages but I don't know where my login and other stuff is - and more importantly it's huge.

I was sort of hoping some people here would have something to help me start. I'm also a noob at tuning in general.

I know I don't want this reving as high as an LS3.

Correction - LS376/480. The GM crate motor.

This is what I meant - not 476 CI.

Found 4 G8 GXP tunes on HPTuners. All are for automatics, 3 are stock, and 1 is a 93 octane tune.

Can I attach it here?

Here is one listed as stock.

Denmah posted these. First one is stock.

Second is listed for 93 octane with the following notes:

"increased timing safely, no knock on street drive tests
leaned out pe enrichment

changed over 100 transmission tables including manual mode tables

grabs rubber in 3rd gear.

increased 20rwhp peak and power everywhere overall"

Good luck, I'm afraid I'll be doing this myself one of these days.

Thank y'all so much.

so damn near couldn't get the crank bolt off, broke a exhaust bolt - good thing the heads were coming off anyway - and I just about couldn't find a chain to save me.

but - need to work on getting the front of the engine together. head tightening was a cast iron B. snapped a extension - scared the hell out of me.

need to charge the battery - but otherwise things are going.

Any questions?
