Thanks Aaron. That make's sense. I'm starting to lose confidence in 928 so that concerned me.

Wow this is the first for me to hear this of 928. I’ve been referred to 928 for upgrades especially for their Super-Vortech package. From what I’ve read on them they’ve been in the game for awhile. Has their products/Customer Service depreciated????

Evidently, I must have been getting belt slip from the Sur Grip pulley starting right after install (evidenced by the amount of belt dust). It made 14.8 psi when Seb tuned it right after the pulley install. I changed out that pulley to the Vortech smooth pulley and the Gates rpm belt and did a couple of logs for Seb. The good news is, I've got zero belt slip (no belt dust at all). It's now making over 16 psi. The bad news is, my injectors are now running at 115% duty cycle. Look's like I'll be upgrading to 1300cc injectors and CJM's twin pump set up.

Why not ID1700's? Same price as ID1300's.
