Here is what I want to do:
Truck:
2000 GMC Sierra with 5.3l OS:09381344
We are in the process of installing a Whipple charger without the piggyback electronics but using 42# Delphi injectors.
I understand that there are multiple ways to get the truck running...starting with the current OS modified for FI to an 2002 OS5 custom OS.
At holdencrazy.com I found a 99 OS tuned for a Radix which I plan to use a a baseline to get started.
Until now I do not have a wideband O2 sensor, something I will probably need to get the charger dialed in properly.
In which order shall I proceed?
- Copy the changed tables from the 99 Radix to the 2000 OS?
- Go straight to the OS5 by flashing the 12212156 OS with the 99 Radix changes and the 2000 content? I understand we will also need the 2bar MAP sensor....
Primarily I want the truck to run in the first place and be safe on the tuning side not to run too lean....
Thanks,
Lennart
