problems with a mod, need advice!

[feroskastroke]

I have a 2007 F-250. i purchased a Dr.performance power module (Gen II). its just a plug in not a programmer. it plugs directly into the ICP sensor. it fools the trucks sensor and increases the fuel pressure. since i have put this mod on (about a month ago) i have started experiencing some starting issues. The truck cranks strong but wont fire up. the other problem i experienced one time and that was when i came to a rolling stop the truck revved up a little and lurched forward some while i was on the brake. when i called the company they told me that the lurching forward was possibly caused by a cracked injector nozzle. i can understand that but it doesnt explain the cranking but no start condition. i have tested the batteries and both are putting out 13v but i have not conducted a load test. any advice or ideas to help me when i deal with the dealership would help thanks! the website to the company is www.drperformance.com

Any other mods?

I suggest an SCT

The starting issue could be the STC fitting, or dummy plugs. It could be more than that too. Get to a dealer and have them check for codes. That would be where I would start

dicth that drperformance and go with a sct, if u have to rig something connecting ur icp sensor that would cause the no start, and the lunge could be alot of things, mine turned out to be a an ipr valve

There's your problem your screwing with the setting making it fool itself, get it out.

Go back to stock, then get an SCT...
