I just got my dv's and 370's put in. I also tightened my governer springs up 3 clicks. I pulled twice without these and the truck ran 2750-2775 rpm's down the track. I have pulled 1 time since addin these parts and ran about 3k down the track. On the road it will move on a lot more and smoke a good bit more. But on the track tuesday night it smoked about as much as it did before the dv's and 370's. Wondering what could be the cause of this? Any input is appreciated. Thanks

 

I've got friend that has roughly the same stuff done to his truck other than a 62/14 turbo and suncoast tranny. His will roll thick black and my still jus hazes. Could it be the injection pump or fuel pressure or what ? I have no clue on this?
