Well, I finally bit the bullet and bombed the goat... I took the truck in for the TSB on the throttle ball and socket. Talked with the mechanic about bombing the 5. 9. He said he had not installed the plate and springs before but was interested. He also said that he had visited TDR a few times (now he's a new member) and read up on the results. He took my truck home and installed the Isspro Pyro and 60# Boost gauges, tabbed the KDP, and installed the #10 plate and 3k gov springs. I picked the truck up on Saturday and, needless to say, the ride home was an experience!!! Absolutely amazing in the before/after difference. Geez, I shoulda' done this a long time ago...
