I have an 03 Mach 1.

I have:

4.10 gears
BBK CAI
Magnaflow Cat Back System w/ h-pipe
Predator custom tune

what am I getting approximately for each RWHP

Why is everyone writing down different stock #'s.

I thought stock on a Mach 1 is 305 HP to the fly amd you take about 15% off for the RWHP which would make it about 260 RWHP stock. Please explain this to me.
