It only does pressure, the tst does timming and duration. Its made by ts performance. It stack very nice with the smarty, I suggest you get a rail pressure gauge. The mp-8 ramps the pressure up pretty fast.

Don't know about the stacking part, but I have had mine for 40,000+ miles (out of 70,000) and it works very well... Much better than the Edge EZ it replaced... Some are concerned about the high rail pressure, but for me, so far so good....

fitz, not tryin to tell you what to do but, if you are gonna stack it on a 07 be carefull. I had a friend who stacked the mp-8 with a supposably "fuel only" box(can't remember what). Melted #4 and 6 pistons.

AND pretty high, I would be willing to bet it goes higher than the rail pressure sensor can read. I just don't have $1800 to buy a guage that will read that high to prove it.
