Having been in this industry for over 10 years now we have all seen several good tuners and companies shut down or heavily fined because of the violations of EPA laws. Everyone has an opinion on the EPA but are they really the problem? They are doing the job they were told to. I see this as a Congress problem. We all know how screwed up they are. Can't agree on anything anymore and are so dug in on party lines I don't ever seem them passing anything beneficial. The laws enacted over the last few years for the environment are strict for sure but they are laws for a reason.
I think what PPEI is doing with having all their ec tunes EPA certified is a huge step for a "customer tuner". Sure mfg like Edge, Banks, Hypertech go to that extent with the canned tunes but what do folks really get out of a "canned tuner". They are setup to work with a stock truck or the one that has been modified and still give you performance improvements. PPEI is working hard, testing different turbos, injectors, and whatnot that won't violate the emissions and I believe we are going to see big power out of emission compliant trucks and cars. Their work so far has proven to regen less, use less DEF and still improve HP and fuel economy on the Dmax, Pstroke, Cummins and Nissan applications. Is it completely custom? Yes, I believe so but I think everyone here will have a different opinion on this being custom or not.
I am looking forward to what is to come.
