5.6k mod problems??

[pwrstroke247]

So I did the 5.6k mod and WOW!!! What a difference!! The problem is the truck is crazy off the line but by the end of 1st gear the truck looses everything!! I almost feels like it just not getting anymore fuel..? And just trying to drive normal I can't give my truck more than like 1/2 throttle other or it wont even accelerate! Is this a common problem? Or is it just my truck?

I'm gonna bet that you are getting an over boost code and its defueling.

Hmmmm ive heard of that... but my check engine light is not coming on?? And I know my check engine light works...

[Jake]

It might not light the CEL. I don't remember. Ask Tyler about his.

I think I am just going to take the stupid thing out! Im getting my chip soon anyways!

You'll still over boost probably.

Really? well is there anyway to fix the overboost problem? (if thats what it is) Besides buying something to fool the computer? Could I just unplug that black box that the boost hose goes to? just to see if that's my problem?

[Jake]

You can use an air pressure regulator inline of the hose going to the MAP sensor, set around 20 PSI.

OR....T/C slip youl need to do a t/c lock mod and apply the TPS sencor in the equation for raceing or get a chip that will allow it to lock after take off.like in to second

[Jake]

If it was slipping it would rev the hell out of it, not just loose power.
