Just curious with all of you that have the sprint booster installed have you had any TPS failures? What happens when you try to get on your accelerator is that the trottle body doesn't know the accelerator input (I think), what I do know is that it can take up to 30 seconds to reach 60mph floored and is very very dangerous when pulling out in front of traffic. Mine failed about 3-6 months after the sprint booster install, and then just last week it failed again. $1K to fix but was under warranty.

Why do you think it is the SB?

I've had a SB for years and in 4 different cars. Never a problem.

The Benz technician thought it could be linked.

never had a problem with mine
