Thread: truck is weak off the line

    Try something like this to start out with. I'm a newbie on the decay so if someone sees something horribly wrong let me know I use this in my LS2 and it works great

    Good screenshots, PE looks good, on the Decay rate I'd go 5 instead of 10 because that's too fast for most PCM's to operate. I set mine at 5 with superchargers as well. Because of your compression ratio, I'd like to do a different setup on the timing table. Let me see if I can figure out how to do a screenshot and I'll edit a timing table that you should find very user friendly.
