Interesting. The TOP TSR12S3 is modified at the factory per Jim Hottinger (spelling?) of Fusion Motor sports. I sure hope this isn't the problem.
I ran it a couple of days ago testing it out and it still died twice on me but did seem to run better. I just chalked it up to the fact that it is a modified engine and that the needles are more touchy than a stock P/S.
I have an email into Jim but he has not replied (been about a week or so). Hope he's not avoiding me.
