    What are some ways to prevent crankshaft breakage. I am currently making a little extra power with bigger injectors and a tune and I’d like to go bigger with a bigger turbo and maybe more fuel eventually. I know there are other things to upgrade as well but I’m mainly worried about the crank...

    I just bought brand new S & S 60% over injectors. The shop advised me I shouldn’t drive it without tuning it first. I do plan on having it tuned eventually but I guess my question is do I need to? Is it going to tear something up if I don’t have it tuned and I drive it?

    So I have found a good deal on an S475/96/ 1.32 T6 Borg turbo and I really want to run it as a big single. What do you guys think of that as a big single and what size injectors do you need to spool that turbo? I was thinking of a stroker 12mm fuel pump and all of the HSP plumbing. What else...

    I have an 08 LMM Duramax. I seem to keep getting a code for “injector leak detected” first it was cyl 3 (p02a5) I reset it after running top end cleaner through and the code came back about a week later. Upon further inspection, the fuel return line had popped out so I plugged it back in...

    Hello I’m just curious I just changed my oil and I didn’t notice before but on my opg it reads just under 30psi which is where that normally sits at idle warmed up but on my cts3 it reads 18-20 at idle should I be concerned?

    A few months ago I had an issue with my truck. I bought a superchips handheld programmer and flashed a performance tune on my truck. I was pulling an empty trailer up a hill and there was a pop.
