Greetings. New HPT user here. Have bought and ran the program enough to remove the cats and monitors, speed limiter, and add electric PWM fan successfully on to my 2009 5.3L Colorado. Also now adding a wideband to the system. Many thanks to the forum, members, and support here and elsewhere.
Next step is to swap a stock build 6.2L LS3 into the truck and get it up and running fairly quick as this is my daily driver. Engine is done and ready to go in. Should probably just pay to have a start tune developed, but considering to try this myself. Considering that there were no mass produced naturally aspirated 6.2L / LS3 + E67 vehicle combos, looking for line item direction of what to modify in the tune when switching from the 5.3L to 6.2L. I plan to use an L92 truck intake which is nearly same as the one I have on the 5.3L, same 5.3L 87mm throttle body as I have now, same MAF, even the same harness since neither has VVT/DoD, etc.....
Tune change items:
- Engine/cylinder displacement data
- Injector flow data
- X
- Y
- Z
Should I possibly be looking at snatching the stock tune from a crate LS3 that has an E67 controller, but then just copy those tables over into my tune?
Just looking to get it up and running as stock 430hp, then slightly tune it or have it tuned up by somebody more experienced to 450hp level or so. Probably keeping it all stock, as 200,000 mile longevity is a very high priority.
Thanks.
