I have a 95 Z28 automatic, the mods I have are MAC headers, ORP, hooker catback, March pullies, 1LE elbow, SLP air intake, LT4 KM,160 thermostat, granitelli mass air flow sensor, air foil, taylor wires, NGK TR55 plugs, 3:73 gears, shift kit. Is there much else I can do without going into the motor? The car is running rich what could I do to fix this? PCM tuning? how much power could I expect with PCM tuning and who would you all recomment using? and also I was thinking a stall converter, would I want a 3,000 stall or something different?

Thanks in advance everyone.

 

I'd go with a torque converter next, you'll see a nice gain with that. As for your car running rich, how do you know it's running rich? Have you scanned it?

 

Its smells like it (could be because of the off road pipe) and its getting really crappy gas mileage but I will scan it just to see what should the reading be on the scanner? Thanks

 

how much did you pay for your headers, and where did you get them. Where the mac headers a good fit? I was looking into getting some and I wasn't sure if the mac where worth it.

 

Definetly get a Stall...it'll wake them 3.73's up!

 

I got the headers from www.LS1speed.com I cant remember how much I paid but you can go to the site and look, which stall should I get a 3000? and what brand?

Thanks again

 

Sorry forgot to mention they fit really good no clearance problems or anything.

 

how's about an electric water pump? and maybe a bored stock tb from NOMAD for $160? an an aluminum driveshaft will free up about 5-7#s of torque and rid some vibration.
