Supercharger issues

[V-force]

I'm having some issues with my SC. I live in Canada in the Northern part of Alberta had my SC installed in October of 2008 and has never perfomed properly since day one. The Truck picks up great from 0 to 100km/h (62 mp/h) once you are at 100km/h (62 mp/h) put it to the floor the truck revs up to just under 5000 rpm and the speedo barley moves. If you push the gas peddle 3/4 of the way down it picks up more like the stock truck or even worse. Can anybody tell me whats going on. Talk to the dealership and all I get is the run around. Dealership responce is were talking with TRD they got to get back to us Trd says it's just the cold weather. We will wait until it gets warmer cause the Sc runs optimal in 8 deg C (46.4 deg F) and warmer which is bs,runs the same in -30 (-22 deg F)as it does at 16 deg C (60.8 deg F). The Sc should run the same summer and winter I wouldn't have bought it if that was the case. Talk to me dealership yesterday said they have a new software update is this goning to take care of my problem. Not taking the truck into the dealership until May 14. I have wrote a lot of sites and nobody can give me a straight up answer just wan't to have a better understanding of the problems I'm experiencing. Thanks V-force

There have been issues with power loss at cold temperatures, for which a firmware update is apparently available. Your symptoms sound somewhat different than what others have complained about, but I would get the update and move forward from there.

the software update should take care of yor problems

Has anyone had the software update? When I receive the update I will let you know the results hope it cures the problem. Thanx for the feedback!

[Mr. Creosote]

Yes a few here have had the reflash with positive results.

Good to hear. How much boost is the the SC pushing? Is it worth adding headers I'm already running dual exhaust. And are the ever gonna come out with a tuner probably another 50 hp sitting there in that SC?

I'm starting to wonder if they reflashed my truck properly after they installed the SC. Guys are saying there's no speed limiter and mine would limit out at 110 mph.
