My experience with the SW chip had been great. This is not to say Russell's chip is not I have not had one. So this is about my experience with the SW chip and customer service I have received. I have had a rich running issue since I did my rebuild and have been working with Steve to help me figure it out. He spent a lot of time on the phone and had emailed items to verify which I did. He didn't want to just reprogram the chip as he felt that there was something else causing it. He was right as I had timed my cams to the wrong mark and had them advanced to around 12 degrees. Set it up right and it is unbelievable. I am using an LM-2 tonight to check the afr's and see if Steve can get any more out of the engine. The price difference will be long forgotten.
The multi-chip option RB has is really great... I could see having a couple of different maps
