Latest update, after a built engine/cams and ported (OE Blower, Lower Intake, Elbow, and Heads), on 93 pump gas & Boostane, still on stock fuel system and injectors.
Mike Weedin (VMP) done a great job with the tune :cool: and the car made 833rwhp/892rwtq.
Previous power mod's,
JLT CF 127mm...
that's correct its based in Kuwait.
you can order them with the vacuum activated valves for the dual mode.
they come with the valves pre-installed, and a small vacuum pump device with 2 remote controls to open and close the valves.
here are some photos of them on my car
you are welcome.
I think as long as you don't overload it with burnouts and hard launches it should last for a very long time, mine started slipping after few burnouts at a rolling race event :D
I'm running both upper and lower 10%, seeing 20-21Psi on the factory boost gauge, and the car made 732rwhp/757rwtq on a mix of 93 pump gas + a can of Boostane.
Last year I changed my stock mufflers to Bullet Performance Valved axle back and I'm so far happy with them, they're very quite when you close the valves.
