My cousin is looking into one of these for his 04 cummins H.O. and I was wondering if it erased the overboost DTC that the dealer looks for to try and void the warranty?

Thanks,
David

I don't know about the power pup but I hear the tst chip is much better.

That's funny. I used to get overboost with my Dmax when it was bone stock.

TST is a much better choice. I had both on my 04.

Pup does clear codes but I don't no if it totally erases them from history... if there is any.

Thnkas what are the price and HP/tq. ranges on the TST? Is it good for towing this truck is used for a hotshot business.

TST claims 180 HP 580 TQ with a pusher feul pump kit.There is ten hp and ten tq settings.I have heard that the stock turbo won't handle more than level 6????.
I saw a Power Max CR on ebay for $750.The CR should include the gauges.
