I have a 1993 z-28 and added a couple things and wanted to see what my power increase and handling might be
Upgraded spark plug wires
Upgraded spark plugs
Cyramic brake disks and pads
Performance tires
Master flow stainless exaust system
Cold air intake system
Stage 2 performance chip
Voltage regulater
180 degree thermostat

 

what kind of cai do you have? for tuning your better off using solomon LT1 PCM Tuning - OBDI/OBDII PCM Tuning/Programming Service or pcmforless PCMforless i have used both and solomon has gotten best results with my setup. have not heard of masterflow, what size pipes? its hard to say on the gains, guessestimate,,, you probly gained 20-25 hp.
