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.
