Step-son has a 1998 C1500 Silverado that was his grandpas truck he got after his grandpa passed away. Thanks to me, he want to modify his truck to be faster. I know the best budget option would be a 5.7L with a 411 PCM swap, but being its his gpas truck, trying to keep it somewhat original, and he can get a different vehicle later on to build for performance. I recently picked up a MPVI3 to use for my Dakota R/T I am rebuilding right now, so am kind of using his truck for getting my feet wet with tuning, before trying to tackle a 410 stroker nitrous build in the Dakota.
Ive done a few small things. removed engine torque management. tweaked the MAF table a little to get LTFT a little closer to 0. increased dwell time on spark. increased shift pressure and increased shift speed. not using a wideband right now. and not trying to tune it for max performance, just a little more get up and go. He will be racing in a teen driver bracket series at local track this summer. Not sure if he will use his truck, or my Ram 1500. The changes I have made so far have helped, but feel there is more that can be done. I removed burst knock retard, but havent uploaded that tune just yet because his is at his dads house this weekend.
Attached are current tune file, and most recent data log from driving. probably need to do a bit more driving to get a better log file. burst knock gone.hpt2nd drive fuel tweaks.hpl
