[juan gomez]

hey guys need help,
truck lacks power
I PUT A NEW FUEL FILTER TODAY,WENT DOWN THE FREEWAY GOT UP TO SPEED QUICK .IT RAN GREAT, I GOT IT UP TO 80MPH AND I THEN I CAN FEEL IT KICK OUT .ONES IT KICKS OUT I CANT GO OVER 70MPH ,IF I PUSH THE PEDAL TO THE FLOOR IT GOES INTO 3 GEAR AND WILL SLOW DOWN . IT WILL ALSO HAVE LITTLE POWER, COULD IT BE THAT MY BOOST IS SET TO HIGH FOR STOCK COMPUTER.I HAVE THE TM BOOST CONTROLLER.MY BOOST WILL PEAK AT ABOUT 11LBS.,AT 70MPH MY BOOST RUNS ABOUT 9LBS.

THANKS FOR ANY HELP,

Sounds like lack of fuel flow. Lift pump OK,OPS running lift pump. Able to prime filter before start up using lift pump.

sound to me like the ECM de-fueling because of high boost. If you run 11psi boost on a stock chip, the ECM will de-fuel to keep from hurting the motor.

You should get the check engine light as well.

I think Tim is on target. Before added new EPROM chip I had the boost at peak at 10 PSI any higher the truck defueled and threw codes. Try loosening the nut on your TM so you get max 9-10 inchs of boost until you get a reflash ECM.
