6.4 tuned vs lb7
 
So my sister's boyfriend has a 6.4 and just got it tuned ,I believe he said h and s tune 310hp and deleted ,other wise stock. Was wondering what you think my odds of winning against him would be. I know there not slow trucks and are easy to gain hp with. I think my sig has all the info on my truck other then its a single cab. Thanks

Sig didn't show up. But if you don't have a built trans and can't launch in 4wd & he isn't lifted to the sky your gonna have a hard time. My friend has a Spartan tuned 6.4 & it gets down. Its always in the shop but runs good when on the road

I have a go pro so no excuse to not get a good video. Only bad thing is winter and he don't want to race till summer by then I'll hopefully have a nice turbo set up. Just wanted to get some thoughts on it and if there's anything I should change. Also any recommendations on a turbo set up with my mods above would be great.

If your not lifted get a DHD centerlink brace. If you are go the cognito route.

How much do the center links run?

Lots to think about when picking a turbo. Do you tow often, give up spool for top end, preference on twins or single, how hard do you want to push stock bottom end, budget? Might have to swap converter to suit turbo selection. I still haven't answered any of those questions myself & hence still have a stock turbo.

Yea exactly what I was thinking about that's why haven't jumped at a turbo yet.
Towing no not really.
Truck pulling I will be doing.
Drags I'll be doing.
I have precision converter.
No preference on single or twin turbo.

I want a good 700 hp range and don't want it to be really laggy or needing it to build boost forever.

If engine blows Id have it done right and build bottom end. For now not worried about it.

S475, 87, 1.0 housing
2500 rpm+ converter
Maybe dual pump depending on how you hold rail pressure
Good tuning

That'll get you close. Definitely walking the thin line of breaking the bottom end.
