Re: 4" turbo back what to expect?
When I put mine on nine years ago I was running a HYPERTECH programmer. It made my truck feel slower(loss of bottom end response).After adding more fuel it worked fine. I used a 4 inch downpipe,so I think that resulted in a loss of response with the low fueling of the HYPERTECH. I run DP
but I am really looking at Beans.
