Ok! time for my first question, but first a little back ground info. I am working on my teenagers 1995,1500, 5.7 TBI converted to TPI. He did the conversion for looks and school project. The problem is the tune needs a little tweaking for cold idle (when the truck first cranks it will go dead, runs ok after warm) and idle when AC kicks on. I got a pcm from someone on another board that he made changes the pcm for 8 injectors instead of the two TBI injectors. I was suppose to receive the mask and bin files but never did. Now I can't get in touch with the guy to get the mask and bin in order to make any changes to the tune. The product was top notch as was the tune except for the minor issues listed above. Can I use any other mask or will I need that specific mask for that modded pcm? Not sure what to do, any advice greatly appreciated.
