Throttle stuck full open on me the other day while driving a friends 98 12v. The pump was just put on and set up for about 500 hp. I slid the plate forward and took it out for a test drive. Once warmed up i put the petal to the floor and it didn't feel like it was running quite right so I lifted and it just kept acelerating!!! :eek: I dove on the brakes and shut the key off but that did not shut it down completely. It finally stalled when I came to a stop. I had to prime all of the lines and have someone with a board ready to block the turbo, but it finally started again. It will not hold an idle and when I give it a little throttle it starts to rev out of control. Any thoughts? Throttle cables and connections all look good. Turbo oil seals are fine, problem must be inside the pump? I just want to make sure before we go back to the company who built the pump. Thanks!

Who set up and phased it ????
 
It was one of the top 3 companies who set up pumps. I dont want to say the name as we are still not sure of the exact cause.
