Had a buddy call me yesterday asking if I was going to a dyno day that him and Brian were going to. Didn't think I'd make it but he called me again the morning and I said "what the hell". What I didn't know is it was a cummins dyno day and well..... The pic says it all ( c=cummins, d=Duramax)
Almost 200hp on them and I still couldn't get the truck to load up the turbos right. Between 45psi and 50psi I gained 20hp and I was still 15psi short of the 65psi I saw in the street on the way home. Probably should have tried 5th gear. Ah well, I was happy lol. My buddies 04.5 cummins hit 543hp on just a turbo and tune, him and I were quite surprised!!
