At first it only did it on the freeway full throttle getting up to speed.I put a TST power kit in #8 and now when it decides to screem in come in around 15lb. Also I'm new to diesels and I'm only getting 70-75mph and the pedal is to the floor is this normal for a 5.9?I have a 4.10 axle ratio and the rpm is around 2200-2300 at 70mph.

One reason being the stock gov. on the 12v is around 2500RPM, but if you are only getting 75MPH with your foot on the floor you better start looking. A loose intercooler hose will limit power/top end. Have you repaired the hose and tried again. Some things to check for are boost leaks, intercooler hoses, intake manifold. Let us know.

It's should take you around 2 hours with a least one coffee break figured in there. Properly setting up the rest of the truck (TV cable, TPS voltage) will probably take you a few test drives. A good thing to have on had is a pressure gauge to test your tranny perssures after the install. Before you buy a BD valvebody you might want to call DTT 1-866-504-4002 and ask for Bill. He is a very straight shooter and won't give you a line of BS. They custom build every one of their VB's to customer specs. No off the shelf, one size fits all. Their customer service is also some of the best in the Biz. You simply cannot go wrong with a DTT valve body. www.dieseltrans.com BTW - Glad to hear you got your low power problem figured out.
