My 93 with some new stacks
Trending Topics
I have my fuel screw out 2 full turns from maxed. I also have the smoke screw all the way out. It currently makes 42 psi boost. When I first put them in the boost gauge went over 50 instantly. I had to back it down to hold it together. I had the smoke screw maxed with the stockers but with these I had to go out all the way so I could drive it without the cloud always there. I don't mind smoke but smoke all the time is not good.
I may have to put that 5" turnout on my truck now. Thanks Richie, I didn't want to cut a hole in my bed...
