why not put the stock FPR back on with the 19lb injectors and try it out? That would be a whole hell of a lot easier.

Speaking from experience with my JET AFPR on my 92, it ran RICH as hell on the lowest setting and I even cut the spring down with my 40lb/hr TBI injectors (305 and 4.3 V6 size).
I put the stock FPR back on and got some 55lb/hr 350 Injectors and it seems to be the sweet spot, but it leans out above 5000. I'm not worried about tuning it anymore, I'm finally canning TBI and going carb now that its a pleasure only car.

I am thinking of running 30#hr LT1 Injectors on my 3.8l Firebird.This should work fine shouldnt it?
I am running cat-delete,muffler delete, 3" open pipe, K&N,MAF screen delete, air silencer delete,L36 C2 cam, NGK TR55 .070 gap and 8mm wires. Rear O2 Sim., and some extra mods on my induction.... V-8 T/A airbox with standard and underside induction. If you need to know anything else, Jenn knows me well [img]smile.gif[/img]

i sincerely doubt you will need 30/lb hr injectors...unless you do some serious PCM tuning, bolt those on and you will be running extremely rich.

LT1's have 24# injectors not 30#

[Pagan]

yes stock they are 24#, but I am actually looking into the 30# LT4 injectors. And about running rich, I will be running MSD and having the PCM tuned. But this will be part of a package I am doing, I will also be doing cam,rods,rockers,springs and such, So, I shouldnt be that bad off.
