88 S10 4X4 3.4L TBI Bin files

I have an 88 S-10 4X4
Truck was a 2.8L LL2 TBI, 700R4, 4.11 gears
I replaced the wimpy 2.8L with a mildly built 3.4L .060 over bore - long tube headers, ARI stage 2 cam, 1.6-1 roller rockers,double springs, Match ported heads to intake, 350ci throttle body, super sucker spacer, intake opened up to match TBI unit, running 15psi with 45lb@13psi injectors, large cold air intake.
anybody have a base tune bin for a similar build?
mail order chips are useless because they are for a stock 2,8L
Thanks in advance for the help.

First thing I did when I messed with one of those was ditch the archaic 700r4 and old ECM for a 4L60E and 7427 pcm. Ran a very similar 3.1 with 61 lb/hr 350 injectors on it.

Yeah but I'm just stuck with the 700R4 for now. The trans survived about 4 months with the new motor then exploded the converter,
i spent to much cash on the trans to dump it for the 4L60.
The 700R4 now has TCI converter and all the corvette servos and clutch packs. feels solid now.
