Hi. I bought my 2012 2500 Cummins used back in October.

I've put lift and 37s Toyos on it since then. The guy before me had 5th wheel hook up there's still some hard ware in the bed. Every question I asked the sales man bout the truck he had no clue. (Truck sold it self)

I did a full delete few days after I got it. I'm running a raceme tuner.

When ever I put the hammer down 80% to 90% throttle it when I'm passing someone on 2 lane highway I see high line pressure I've seen 192PSI 198PSI even seen 204PSI now I thought the 68RFE transmission was stock but I didn't think a stock pump would do much over 185PSI.

So I'm pretty confused. I truly can't complain about how it shifts. I do love the converter lock up in 4th just feeling all the power getting to the ground LOL.

So should I think the Tranny had a little work done to it? I plan on driving the same witch is ***** footing around but let's face it sometimes u gotta feed a lil speed to your ride. So what do u guys think stock 68RFE or lil work done to it?

Thank you in advance.
