ok ive had a few mods done so i got the uprev tune,, now im thinking about doing the transgo shift kit. if i do will i need to use one of my tunes after the install or it should be fine since the truck has already been tuned with uprev?
I'm no expert, but from what I've seen MOST of the people running Transgo don't have upgraded TCs or VBs.
The shift kit seems to be everybody's first tran mod. I personally want to have my VB and TC upgraded, but am waiting until I can have the complete rebuild done.
