Problem with TRD supercharger - Toyota Nation Forum : Toyota Car and Truck Forums

I have an 08 limited 5.7 and had the supercharger installed about 8 months ago and its never ran right. Whenever it gets to 4k rpm's the boost drops to 0. I've brought it in and all I've been told is that TRD is working on a new reflash to fix the problem. I was told it would be done by early March but its still not done. Does anyone know more info on this or what else could be wrong?

I thought the new flash was available??? If you have another dealership nearby, it might be worth stopping in and talking with them.

How much did that install set you back?

you should check your vacuum hoses. it sounds like your losing vacuum when your supercharger is starting to create boost. that drop off in boost is usually related to a vacuum problem. also check the fittings around the supercharger.
