Hey everyone, so I've weighed the positives and negatives of the LS4 and decided that I can't keep driving around with it, way too touchy for the driving I do, even touchier than my old Ralliart. So my question is, do I need to send my PCM back in to have it retuned to use the stock TB? Or would everything work fine if I just bolted it on?

 

will need a tune I believe

 

Damn it, that's what I was afraid of. With college and work it'll be tough to send my PCM in, oh well haha.
