Just got my mp8 back from getting reprogramed and go to put it on and my truck wouldnt start.I finaly got it started and it sounded like it had a very big cam in it. So i took it off and than my truck started just fine. So what do I do im going to call ts tomarrow to see what i can do.

 

What did you get it reprogrammed for?My mp-8 did the same thing intermittently.The plug on the map sensor had a slight touch of corosion.Put a little di-electric grease on it and fixxed it up

 

Sounds like you have the connectors backwards.

 

I bought from a friend that had a 2007 and tryed it befor and it did the same thing so i called ts and they said that it need to be reprogramed for an 04.5and 05 so i sent it in and paid the 50 bucks and got it back and it is doing the same thing that it did before. I had an edge ez before and had no problem with it doing that.

 

Theres only one way to hook them up.

 

did you send the wiring harness in when getting reprogrammed?Sound like a bad connection or faulty wire.I've unplugged the harness from the box and forgot to hook it backup and started the truck.Real ruff idle and heavy camming.Also set the CEL.Do you have any codes?

 

you can very easily hook it up wrong. with it plugged in did you get a water in fuel light and a very rough idle?? If so you had the plug backwards

 

I got mine in the mail, plugged it in, and the truck ran rough as hell...So then I called ts and they asked me to pull the card out of the little container. On the back 4.5 was scratched out and 06 was written over it. I have tried again and again with no luck so I am going to send it back. My guess is it was never reprogrammed. Anywho, good luck man.

I got in my truck this moring and had my check engin light on and check it with my smarty and i had 5 codes. And yes i did sent in my harness in with it.

LOL.........

 

I guess it isn't junk after all, eh?

The MP-8 is the best pressure box I've run, and I tried a bunch. I have yet to try an X2, though...

 

I bought one and installed it. I had it on only part of the way up and my truck ran very badly. so I removed it and returned it the next day. I have had good luck with the diablo power puck for some pressure. other guys really like the mp8 but I had no luck with mine and it was brand new not used
