Ok guys I need some help. I just bought a 2000 SS with bolt ons. Long Tubes, O/R X pipe, race bullets and dumps. SLP Lid, Ported TB, Trans cooler, stock trans, stock rear, some suspension work. I am looking for some help with tuning with the Diablo. I have always had a friend tune my cars with HP Tuners but I am holding off with a dyno tune until I put on the Cam, Heads, intake, Stall, built trans etc. I want to tweak the car some with the Diablo, enough to get some benefit from the mods I currently have and safely drive it daily until I dyno tune it. Dont flame me too hard, Im trying to learn.

Here's my questionable areas in the tuning:

Power Enrichment - Fuel tuning
Spark advance/retard - Timing reading high 30s to 41 degrees under cruise!
Injector Slope
etc

I know every car is different and the best thing to do is Log some data and adjust off of that but I haven't got the logging down yet. I tried doing the LTFT Logging but didn't drive long enough before logging so i got high % numbers. Also my model doesn't show AFR so idk how that's running.

I put in the Diablo Tune and only changed tire size, Torque management off, line pressure up a little (Previous owner had line pressure all the way up.) The car feels like a slouch currently. I just feel like it should perform better. Is there a standard adjustment that i can do to Timing and fuel to see some gains without it harming anything or being a concern without this cars data? Are there tunes on the net out there for Bolt on LS1 cars that I can download and try out? FYI I saw no misfires during my cruise included WOT, Only saw some knock retard under WOT but May of been the Kick down shift instead of actual knock.

I've uploaded some pictures to show it off a little.

Ok So i just dug around some and found a DIABLO TUNING 101. I will read it and See what i can do. Sorry for posting before doing more research. Any help is still very appreciated as you guys have much more experience with this than I do and I am still interested in seeing what tunes are out there I could download and install if possible.

What did you find out?

there are no diablo tunes to download... and you can not use anyone else's tune files from their vehicle, because tunes are locked/married to a vehicle's VIN number and engine calibration ID's... they will only work on the vehicle they were created for...

you can find more helpful info on diablosport's Predator GM Gas forum as well:
