I have a 94 LS and have AEM CAI, DC sports exhaust and header, MSD ignition and coil, AEM fuel rail and regulator. I was debating on weather to get some crower 403's or get an ecu upgrade. Does anybody have experience with either of those on a setup similar to mine? If so what kind of improvement, disadvantages?

 

def cams, not much more then the ecu and you'll def gain some hp

 

hmmm, I'd say cams first, but then I'd also say get the springs and retainers, personally I went ECU first, knocked almost a half a second off my quarter.

 

Cams

 

cams then ECU

 

get some cams, then get your ecu programmed..everything works together...

 

i'd say get the cams first, like the rest
