Problems after changing exhaust system
I just put a MBRP 4" turbo back system on my 05 truck with the cat delete pip and I lost almost 3 mile to the gallon. I am using a tuner from DP Tuner. I had a 4" cat back system on my truck and was averaging between 17 to 20.2 per gallon before I put the turbo back system on. I am looking for advice before I put the cat back on. Has anybody tried this? and what did you do.
