Ok, I'll try to keep this short. I upgraded my injectors to 30lb and bought a 80mm Pro-m meter cal'd for them. Installed both and car ran like crap. I had to bring the fuel pressure down to 30 vaccum off so it wouldn't back fire. Went to a chip burner and he gave me an SCT chip for 30lb but I had to put stock Maf back on. Chip hasn't been tuned yet for optimum results. I sold the 80mm because i bought it at the time Pro-m went out of business. So I figured the cal was bad. Since I bought the chip I wanna use it but I need a bigger maf. How do I decide what the maf would be cal'd at if the computer has the chip and already cal'd for the 30lb injectors.?? Here are my mods:
89 gt
stock block bored .030
stock cam
gt40 Y303 heads
30lb injectors
190lph pump
cobra intake
70mm TB
1.6 rr
3.73 gears
also, if anyone is in the Wa. area I'm in Whidbey Is. and would need a tuner. Thanks for you help
