[QUOTE="Toni, post: 15881817, member: 191140"] My previous car build by myself was a 2012 gt500 with vmp supercharger, 2,4 pulley, 15% OD damper, long tubes, 64mm ford racingTB , JLT intake, Brisk plugs, McLeod clutch, carbon fiber shaft, no Cats, eaton true trak differential, and boost was 22psi. Tune was made by Justin Starkey and then modified for upgrades by Alex Flores. This car never had any problem, runs very strong, never did any hesitation. I always use Brisk plugs, never had any issue, your car will be good with Brisk GR14YS recommended for all 07-12 GT500 under 18psi. My gt350 issues are cruising at light throttle, at wot runs excellent, I’m convinced my problem is the wrong bypass vacuum actuator, must be a low vacum actuator(0” Hg closed to 5”Hg open) but to be sure I would like to know if Gt350 whipplecharged that are running good have the standard vacuum actuator or the low vacuum actuator. Maybe my whipple supercharger kit comes from whipple with the wrong actuator. I check my vacuum actuator with a brake vacuum pump and a good vacuum gauge, runs free whith no mechanical isues. (5"Hg vacuum close to 10"Hg vacuum open). I have installed a boost/vacuum gauge in my car and could see when hessitation happens, and can go for this hesitation with my throttle going to 5"hg of vacuum when hesitation appears.
