There is no way to know without a wideband to read the air/fuel at idle and cruise. Odds are you can probably get away with mid 40's fuel pressure but it's really a guessing game without a wideband.

True he does have some pretty nice parts! They claimed with the 42s there was no change in drivability they also tried 52's and said you could notice it then.. I'm with you they prolly didn't even have a wideband back then to see how much fuel they were pumping out the tail pipes driving around... I love that article I think ive read it like 100 times... Love the part when they say" we finally found how to coax the power out of this little sucker" did they have widebands back then? I know they prolly had them on the dyno They had widebands on dyno's back then but who knows if it was being used. Regardless, the car will "feel" like it's driving ok with an idle/cruise AFR in the 12's but the MPG will go down a TON at that point. I've also seen people say their car runs "great" and I get in it and feel like it's not going to make it around the block. |

Shoot with my blow thru carb my cruse is low to mid 12s I could live with that I don't drive it everyday tho... They may have not even had the walbro 255 at that time as the opted for the t-Rex boosta pump in the tiny avenger saga.... So stinger have you ever personally messed around with 42lbers?

For now I'm just going to go with the 255lph and the AEM wideband. I'm going to order the PIMP ECU/injectors as soon as money permits. I already have a kirban unit for 1995 gt. It should work right?

Yes, I had 42's in my 91 LX but I had to dial the fuel pressure back a bit to get it to idle/cruise at 14.7:1 (making the injectors smaller than 42's so they'd work properly for a daily driver). |

It is, but it's no different than running 35's with elevated fuel pressure (the fuel flow is the same).
