I was just woundering where the f.p.r is located on a 93 firebird formula?
The second part of my question is, the car seems to be running border line lean and was woundering if a a.f.p.r. would help with this prolem?
The mods that have been done to this point are hypertech chip, cold air intake, flowmaster cat back system, and msd ignition box and coil.
I pulled out 1 of the plugs and it looked like a brand new plug, no carbon on it at all.
I was told that I may have to boost the fuel pressure aswell as get another chip custom burnt for it?
Im not sure at this point in time which way to turn, any help would be greatly appreciated

 

Test the fuel pressure make sure it is in spec, then get a custom chip. IMO the only good product Hypertech sells is the 160 LT1 stat. pcmforless.com as well as others will be able to do a better job on the chip than Hypertech and probably cost less.

 

Can anyone tell me what kind of benefit I can expect from changing my thermostat to a 160 degree?
I would also like to know about installing an adjustable f.p.r if that would help with my lean condition?
