i think i broke something

--------------------------------------------------------------------------------

well here we go again. when i installed my whipple the first time i did it by the instructions and deleted the egr stuff. On the first test drive the truck pulled good and ran great. BUT from a dead stop (WOT) the truck would not spin the tires or pull hard at all. It just acted like it had no power. From a roll you could go WOT and it would down shift, the blower would scream, boost gauge would shoot up to its stopping point, and the rpms would jump up to around 4-5k pending on mph and gear. BUT it would not pull at all. And the truck's trans feels like it is slipping but the rpms and engine sound did not seem like it. I emailed JJ and he told me to run my vacuum lines like the JDM racer kit because it sounded like i had the boost actuator hooked up wrong and the truck was not making boost down low. Well i just finished the install of the JDM racer kit line system and took a test drive. The truck does the same thing as it did before. Plus the truck would not shift out of second gear at wot or go above 5k rpms. Is my transmission shot? could my converter be bad? the truck acts okay under 1/2 throttle though. my plugs looked okay (i pulled the front 4 four plugs while i had the whipple off and they looked good). my mods are in my sig. also. any ideas?

Sounds like something simply wasnt hooked up right during the Whipple install.
ie; Vac Lines, Sensors, Harness Connections, etc...

I would find a Brother with a Whipple, open both hoods, and double check each and every Vac Line, Harness Connection, Sensor Connection ....
