Advice please
Lastly as I live in England and cannot get it dyno tuned, I need a handheld as I intend to get some mid lengths and catted y-pipe. i have seen an SLP Diablo tuner and would like to know what you all think or perhaps you have used one. All help is much appreciated.
There is no insert for a tb that can do the same thing as porting it. just read how to do it and port it yourself. an insert wont help you.
for midlenghts and a catted y-pipe you dont really need a tune, but it never hurts
