Incorrect. RENNtech has only ever sold one Pulley kit. It used to be that you could purchase the pulleys separately from the ECU upgrade but they were the same pulleys.

There is no "low boost" vs. "high boost" pulley kit.

If you guys feel that you are running more boost than the ~ 3 psi number I threw out one of us is wrong with their figures and I am perfectly willing to accept that I quoted the wrong value in PSI increase.

 

I appreciate all the help guys. I am going to start by removing the Sprint Booster. I had the hardest time getting that damn washer out...not looking forward to that again. I'll let you know if it does the trick.

 

Use a magnet to remove the washer.
If you don't have a magnet, put some tape sticky side out over the end of a socket.

 

There is one more thing I wanted to mention about this issue. This doesn't happen (foot to the floor and no boost) all the time, but I know when it will happen. When I am driving, I feel a little jolt (like a rough gear change) and then I lose all boost...not sure if that tells anybody anything.

 

Sounds more like the Sprint Booster is causing your drama instead of the pulley. Not sure though.

 

I am sticking by my statement that the pulley is not the issue.

The Sprint Booster may or may not be the issue but it is the easiest variable to remove from the equation.

If you are able pull any codes in the ECU. If you have IAT warnings it is the intercooler pump.

 

Alright...after having the car at the dealership for nearly a week, the problem has been resolved. It was the secondary pump problem. I printed out the posts from this forum, and it was fixed the next day. Anyone having this acceleration problem, take it to the dealer, print out the posts and they will be able to fix it.

 

My car is at the shop getting i/c pump replaced as well.

I'm curious to see how many of us had their pump replaced and at what miles to get a sense when the next time it will fail.

I'll start...

i/c water pump broke at:

31K miles
