Makes me wonder because I'm getting a sound if I let off under slight boost *5-8psi* that I normally only get with Sp@rtan/P!P if i'm around 20psi. It reminds me of the 11-14 twin scroll "rick flair woooo* only no where near as loud.
Also would anyone be interested in a review of Tyrant Diesel *Cale Thompson* tunes?
I'll get a hold of Tyrant tunes soon then, probably next week. Gotta renew my CDL and some other stuff early in the week but later I should be able to get them loaded and tested. I've got a nice off roading planned Saturday, so it'd be a nice test.
