Bully Dog for Cummins 400 HP

Is it an ISL? I'd call Mark Chappell at tst products.com. He was a Cummins engineer for 32 years. I have their PMCR on my 03 and I gained nearly 2 mpg towing by fine tuning the parameters as I drove down the road. It also passes emissions with 1/10 the allowable limit. Craig

I would like to address the CA bashing. If it was not for CARB you would still be driving a performance car with 300-400HP that returns 4-8 MPG. Because emissions requirements forced the manufacturers to work on piston, cylinder head, fuel and ignition efficiency you can now have 300-400 HP and get 20 MPG when driven sensibly. You can also have 200 HP that returns 30+ MPG. Yeah, CA sucks.

Not all tuners are off road or race only, infact if installing the tuner burns less fuel it may produce less pollutants. Most all the new tuners keep all emission equipment intact.

May lessen the pollutants? That's laughable. Just because you burn less fuel does not mean you are generating less pollutants, based on type of pollutant. Lessening fuel consumption involves raising the burn temperature of your fuel to generate more efficiency. Raising the burn temperature is certain to raise the NOX output out the tail pipe, as it takes a hotter burn to reach the threshold temperature to cause the Nitrogen and oxygen to chemically bind and form NOX.

Can you present to us any tuner that has had their Tune approved by CARB and the DOT for meeting all pollution standards?

I know the tests and pollution standard certifications are quite expensive, there's a ton of world wide VW diesel product that enthusiasts would like to see in North America, but the testing fees are so high, that VW.de can't justify the additional expense to have each engine model tested to CARB and DOT pollution standards. Therefore, I would find it even more prohibitive for a tuner to pay for testing on all the various tunes they offer out there, as being street legal. One minor parameter change, and the whole chip tune program needs to be retested and certified. That's unlikely to happen.

Frankly, because I live in CA, and I've seen so many gross polluters and coal roller trucks brought in from out of state get cited by either CARB or the SCAQMD, we had diesel sedans banned here in CA from 2002 to 2009. Pretty much because of the truck boys, idiot tunes, and p*ssing off the clean air Prius smug liberal hippy's which lobbied CARB to ban all diesel sedans from CA. I really don't want to see diesels banned again in CA. Clean air belongs to everyone, it's everyone's responsibility to help maintain it.

Sounds like your problem is California not the rest of the country. You ever thought of moving to a friendly state? It may rub off some.

So you have no proof that the tunes you propose are DOT/EPA approved? I thought so, so you attempt to deflect to California being the problem. You see, it's a federal problem, not just a California problem. The problem is gross, visibly polluting trucks that have chipped, tuned, or modified non certified factory fueling and boost maps from those approved by the EPA and CARB.

It IS a rest of the country problem. Ignorance is bliss, it has nothing to do with California being a non friendly state. Clean air is for every one.

DOT /EPA regs.

I have not run Bullydog products. You don't say which year Cummins. Be sure to use settings that avoid excessive pursue for power gains. Your choices are timing, duration and pressure. Avoid pressure. I use a Smarty programmer. I see about 100deg reduction in towing EGT's (exhaust gas temperature). This means turbo temp.

Before adding any kind of power buy and install gauges.

Genosgarage. Com is a great place to start. Also look around for local vendor that your friends trust.
