fuel setup for ttrim on my 331

If you check out the link below you can read all about my new supercharged DART 331.

im currently running 42lbs inj. and a lightning MAF and I have yet to catch it going lean.

The fuel pump has A LOT to do with higher rpm lean-outs too. make sure you have at least a 255gph in-tank.

my old 306 REALLY leaned out at 5500 + with the same fuel set up as i have now EXCEPT I had a 190gph pump.

......and at 5500 rpm, its VERY hard to visually catch lean conditions on a digital wide band

so if you dont know what you have in terms of a fuel pump, buy a new 255 and install it.

other wise 42s and a LMAF should be minimum!!

read it ^^^^

as for the LMAF, go with the newer 90mm. the FORD pn is f68Z-12a690-aa. this is the proper wiring adapter.

check ebay.... they also have inj. maf and maf adapter combos you can buy in a package.


..... Read my combo in my link, with that i use stock FPR and fuel rails and maintain a fat 11.2 all the way up.
