What HP increase can I expect from these mods?
I just bought a 91 red zr1 with 9000 miles and it is completely stock. I want to add a flowmaster exhaust, change the prom chip to a DRM and install a forced ram air box where the front license plate goes. What realistic increase in HP and TQ can I expect from this??
