I have run the Catcher, TST PM3, and F1 Mach 1. 6 injectors on my 2001 HO all independently of each other. The Catcher made a far bigger difference in performance than the either of the other 2 alone. Put them all together and WOW! This was done when I had the stock turbo.
I installed the TST first, then the Catcher. Turned off TST. I then installed the injectors, put stock ecm back on, turned off TST. I now have the Smarty and I run it on SW#7. Easy to drive with little smoke. I tried SW#9, but it was too easy to create a lot of smoke.
