Just off the top of my head at the moment you might try checking to see if all your ground wires are in place and tightly secured. I know some here have had trouble with translators in the past too. After watching a fellow club member run DEEP into the 10.0's this year on a stock MAF, it is my opinion that the LS1 MAF upgrade is not as helpful at previously believed. If you still have a known good stock MAF available, you might try it out to see if the problem continues. If nothing else you will have eliminated another suspect. It could be one of many things and might need to be checked out by a pro. If you are in the Dallas area, I would recommend club member Jack Laswell.
