I've been running Matt's SRL+ in my truck for a couple of years now, and it's really done good. Here lately, it started shifting kinda funny and when im really in to it, from 1st to 2nd it shifts at about 4300 rpm. A couple of times it actually hit the fuel cutoff right before it shifted. Am i gonna sling it apart if I don't watch it? I plan on reprogramming it tomorrow to see if that clears it up, but I am just curious how many rpms this thing will handle?
