SHE NEEDS MORE AIR

Steerable driver. Not daily driver more Sunday driver maybe try it in a truck pull. Never done one. That's actually down sized from what previous owner had on it he had an s500. He was a younger guy was trying to build a steerable pulling truck. The s400 currently spools around 2400 so from 2400-4k you got lots of pull. But driving threw town/ highway cruising speeds it doesn't really spool. Terrible mileage for a Cummins. 12-13 avg I need to get a new pyro for it cus the one he had in it was dead when I bought the truck. Only had the truck for a couple weeks. Maybe a s300 s500 compound setup? I don't think twin 300s would move enough air for the top end.

Not really upset it smokes but smoke is lost power and ive been pulled over twice now for the smoke being to thick even if I'm trying to drive her nice (hard not to have fun with 800+ ponies)

You have much to learn. I bet you dont have 650 ponies... loose the 5x20's put some 5x16ish injectors in it. If your dead set on an s4 put a 64/83/.8ish something on it with a t4 foot. Your so far away from a good running street truck its hard to help you here buddy. Way to much fuel and way way to much turbo

Build update. went down to a 66/81/.9 spool is much nicer but I have a lot of detuning to do fuel side. Just a side note. Why doesn't anyone run like a 81/82/.9 I ask cus I built one with spare parts and took it for a test run before putting on the other turbo. Spool was actually rather quick. Decent power band from what I could tell without even pushing it. Seemed like it has a lot to give.
