Hey...i’m in Oklahoma..
What is the original PROM or Chip Code for the 1994 K1500?
Is the RV Cam a roller cam?
What are the TBI injector part #'s?
Stock TBI pressure regulator spring?
Likely updated spark tables will get you started, so you can tune the fuel tables.
Adding a Wide Band O2 Sensor (WBO2) will help tuning the fuel tables: see link to WBO2 tuning: http://www.gearhead-efi.com/Fuel-Inj...g)-Spreadsheet

updated spark tables? How do I go about doing this and where are they located, Im using tunerpro RT. Non roller and ill try to post injector #s asap . I have made the stock regulator adjustable, what pressure do u recommend that I should be running?
Add a few degrees timing under 1k rpm and should help it start and run with the cam I think is what Dave meant.
On TBI 14psi seems to be the sweet spot I think,anything over and it doesn’t like it as I recall.

What is this labeled as in tunerpro rt?
injector # GM 8295 5235206*ACR
R these 350 injectors? I just bought a TBI off of 454 BBC what all do I need to change when I install it
Perhaps the TunerPro tutorial (posted by the late eaglemark) will help: http://www.gearhead-efi.com/Fuel-Inj...-a-must-read!-)
523506 injectors are 350 injectors that flow 61 lbs/hr.
Update the injector flow in the .bin file if using 454 injectors. Injector flow information link, including 350 and 454 injector flow rates: http://www.gearhead-efi.com/Fuel-Inj...d-part-numbers
