Hey guys im running an 87 shelby daytona z

done alot of up grades, 255 fuel pump, FMIC, water meth injection, stage 2 logic mod, anyway last year when i hade this stuff on there my A/F guage was reading pretty lean until WOT, had some other problems and didnt get to finish it until now, but i was thinking about putting on some +40's to maybe help that out? what do you think... im running close to 18-20 psi... any and all help would be nice..thanks guys.

you'll need to either run an AFPR and a RRG AFRR or have a custom ECU made to run them at the stock pressure.

why is that?.... and where can i get a ecu for it? im running the stage 2 from forward motion..? or does that matter....

You're running 18-20 psi on stock injectors and on stock fuel pressure?

because if you don't do it that way you'll have +40% more fuel almost everywhere and it'll flood the motor out or just make it way down on power. You really need a wideband a/f gauge setup to see just how lean you're running. The Stage 2 cal is worse for high boost than a stock puter. Why? Because the stage 2 leans the WOT fuel curve out vs. stock.

I'd do some research on the MP stage 2 that you are using. Find out where it's sweet spot is for boost. 18-20psi seem's like it would be to much for the MP Stage2 ecu. Do some searching and find what MP requires for the use of a stage 2. If you are dead set on keeping the 18-20psi then contact TU for a custom cal or FWD-P for a Stage 5 and add a wideband to the order! A narrowband A/F gauge isn't going to give you anything really useful for tuning, rather a few pretty bouncing around lights

There is some interesting information on programing your computer at MoparChEM.com if you are pretty good with computers. One problem you can also run into with high boost on some computers is most MAP sensors are only 1 bar sensors (i.e. 14.7psi) and after that dont know what boost you are running. Thats why when these cars were new we had to add additional injectors for high boost.
