Well i have tried the quad box I did not think much of it because i am a bd fan, bully dog originally came out with the power pup which is a great downloader and will definetly throw the smoke, they recently came out with the tripple dog with the crazy larry capability which is pretty extreme and if used you should probably change ur tranny or clutch. A good stack is the van aken pressure box and the tripple dog , I am curently running it and its great. I stand by bully dog and have seen the dyno results on a stock truck, they give the power, and are very accurate.

 

think we (Jeremy from quad and myself ) figured out the problem with my box, I got the wrong harness with my box apperently there are two of them and I got the wrong one,he is gonna send me the correct one and hopefully it solves the problem.

 

well i fifgured the bd sounded intresting, thought id give the tial version a shot..

well, after 5 trips to the closest place that had it (hour drive each way), 4 diferent units etc, they have never goten one to work yet, ive lost my confidence in the product and wil probably just buck up and get a tst.
