Hi looking for some info on a powerland ecu?? Put it in and sounds like theirs a rattle when put the foot to the floor down around 1500 to 2500 rpm can't seam to get it going right .. Put back in the orgional ecu and no problem.. Do I need to change the plugs or advance the timing?? It's just like when it's under pressure its overfueling or something Need help any info on this would be brilliant .. Love to get it working as it's a cool peace of kit
