CHECK ENGINE after installing SPRINT BOOSTER for MONTERO SPORT 2011 A/T

HELLO SIRS!

After installing Sprint Booster, and running it after a few kilometers... the check engine just light up. I've been running with it for a while now since the Check Engine will not light up always.

It's just this time, that I notice a loss of Power when running my Montero. By the Way, I also installed a DTS CHIP but have no problem with it until i installed sprint booster.

Any same experience out there? and advice.
