I worked for a couple years for TST, Mark the owner, was on the engineering team for the ISB program and knows his ****. You would not believe the level of engineering into those boxes. The PowerMax3 Comp was the king of its day until timing and EFI live came out for the CRs. I still run a PM3 in my 99, though I had Mark take the Comp tune out. Just too aggressive for the 2nd 99 which was the tow rig. Probably have it put back in now that it’s gone the way of toy vs hauler.
