Hey. I’m looking for a VIN for any 98-99 with 5.7 and 5 speed. I need it to program a PCM we did a 4.3 to 5.7 swap into. I’ve tried HP Tuners and it isn’t working in terms of the PCM still thinking it has an auto trans. I have VINs for V8 trucks, but it acts as if the fuel cuts out around 1500-2000 RPM with the clutch pushed in, even slightly. It’s like the PCM is isn’t liking the load and cuts out the fuel. I’ve narrowed it down to programming at this point. If not comfortable posting it on here, we can work something out in private messages.
Thanks
