yea i have 91 in the tank and i can check for vacuum leaks but the other thing iwas wondering if it was getting to much fuel. i am using the boost a pump because i have a kenne bell supercharger and i havent quite figured out exactly where the dial should be ne one else have ideas

 

Hope that isn't a bad case of detonation...

 

jjxtrf150,
Talk to whom ever installed you kit. They should know the setting on the boost a pump. Otherwise, I would call Kenne Bell and ask to talk to a technician. They will be able to set you up quick. Good luck, and lets hope its not detonation.

 

I had a Sean Roe Blower on my Viper that I installed, initially it did the EXACT same thing. I dont know what the PCM set up is on the f150 with a blower but the VEC (piggy back computer) the Roe Viper kit came with had to have a new program loaded, Sean programmed me new smart cards and I was on my way.

In my case he just pulled back the timing a bit.

How much boost are you running? Stock injectors? Stock fuel pump?

Blowers are never just straight bolt ons. They take some tuning and massaging to get them right. You'll get it where it needs to be. Go easy on it until its fixed incase it is detonation or a lean condition.

GOOD LUCK! Im willing to bet its a fuel and timing issue.
