Wondering about what I can run (best - worst) under cold morning conditions at sea level after these modifications.

BBK Equal-length long headers.
MAC cat-back exhaust.
Full cone intake (K&N) located in fender.
15" Michelin Pilot tires with stock rims.
Aftermarket off-road h-pipe.
Custom Chip
3.73 Gears


1990 Ford Mustang LX 5.0
AOD Transmission.
All new wires/plugs/gasket and just about everything from Ford Racing.

Any ideas?

Thanks,
