Im building a 99 cummins to put in my superduty and my question is what is the best programmer or tuner available for these engines. Ive always ran edge on my powerstrokes but i have never pushed them very hard. The cummins is getting 125 or 150 ddp injectors and possibly a pump and twins down the road. Im just curious what set up i would be best going with as im not familiar with electronic performance on a cummins. Any insight will be much appreciated. Thanks
