Removed the TST PowerMax and installed the SJr today. Seems like the TST made a bit more power (maybe) at the top end when set to 40HP (2/2) than the SJr set to 1 but it (Jr) has better response down low and no smoke unless I really try and even then, very little. I dialed it up to level 2 (70HP towing) and it doesn't seem to have much more power than level 1 until higher RPMs. All just my perception of course. Any thoughts?
Another thing I noticed, w/the TST I had to use my right foot to keep the boost under control (I have an adj elbow) and with the SJr, it stops rite at 28PSI. Wonder why?
