    Duramax in an old 6x6 in Germany

    Correct, vans and Kodiaks were coded lly for several years after the fact. To answer the question, you need to just get yourself a regular pickup truck complete harness and cut it down to fit your needs.

    Fuel rail pressure

    I will go a little farther in depth on the explanation of this sheet. So the readings on the sheet are a volume which can be directly translated to a hp number at the crank available if everything is good. On a boost only setup I will go 4xmm3=Hp at crank and a heavy nitrous with boost combo...

    Aluminum Radiators?

    100% failure rate with them, I will only use the stock ones. I have never had to replace the factory radiator in any on my Dmax's but everyone that came through the shop with the aluminum ones would normally only last a year or so.

    That's a timing system error which is why the time can be correct but the mph is way off in left field. They use multi sensor setup to get speed and time and the speed part malfunctioned.

    NHRA was the big "has to be backed up with in x-amount to count as a record" and a few of their sister organizations. Rest of the world doesn't care, if you do something that hasn't been done before it is a record plain and simple. We can all do the math and can call a bs number when we see it...

    Nope, same engine he has been fixing up the past few years! Did this on a single Exergy Alpha cp3 and an S485 turbo on a full liquid street motor that drives great is just plain nuts! I told him it would run a 7.99 so he had to prove me wrong lol!

    Well, so far so good for (#12 on the list) Wyatt, first pass of Sickweek got him a new pb! He shook the tires hard and peddled it and still managed to run an [email protected] with it and load up and ride out to the next track! Everything else is still the same on it. If he can get it to leave...
