Noob with a TBI

Hello,

I'm just getting started with chip tuning on my k1500 TBI. Just ordered to parts to build my ALDL cable, and looking forward to what I'll find. Hopefully I find why my truck is so gutless up hills and am able to help it with tuning. My truck is a bit of a frakenstein: 92 k1500 350 TBI (but '96 vortec block and TBI heads n intake...), roller cam, catless, and many other small mods.

Still very very confused on how you determine which values to change in the injector and ignition maps.

Just want to say thanks to all that have contributed on this forum, it has been an immense help.

Justin
