05 CC not as Potent as 04 SC with SCT???
I just got my custom tunes from Vivian and installed them on my new 05 and the seat of the pants feeling isn't what it was on my 04. Differences in the trucks are as follows;
05 F-250 4x4 Crew Cab
Stock Exhaust with Cat delete muffler still in place. EGR up pipe welded shut with EGR shut down via the SCT.
04 F-350 4x4 Extended Cab with 4 inch Turbo Back Magnaflo system with Cat delete. EGR still functioning.
Can the exhaust make that much of a difference or is it in my head. To give you an example, I could not launch the 04 in 2 wheel drive without breaking the tires loose. The 05 gets loose but nothing like the 04
