"My purchase went thru without a hitch, recieved module 3 days after placing order. Simple installation. I have noticed a marked inprovement in acceleration from a stop, and it seems to have more responce at higer speeds. Will be checking all around performance (gas mileage, etc)with a long trip next week.
Overall it seems to produce advertised claims.
Very pleased with entire process!!
