Hi there

New here and Think itīs awsome with the knowledge you have here.

Looking for a good bin file to start with, hopefully just fine tune for me

The Engine is Vortec block with lt-1 pistons and cam (205/207, 117 cl ) and ported 193 heads. So the Engine have a lite more CR and litle more cam, and breath better ( ultimate tbi mods also)

The car is a G20 van with th700 , it idle ok butt litle rich i think and i belive it realy need a good chip work to wake up.

Live in sweden and the octane here is 95, and "trucks" pre 91 have no emission regulations so no cat or EGR on the car.

Thanks and sorry if my English is not that good in Writing // Mats
