I would like to build my truck to run like 650 on a medium/hotter tune like a stage 4 tune make 650. I knwo it will need a trans and I plan on doing a turbo and turbo piping but what else is needed to support that power? Like 500 hp on a very safe tune is what I want for daily driving.

To make 650hp reliably you will need a larger turbo, built trans, bigger injectors, bigger/second CP3, lift pump, and tuning.


Built trans/stock turbo/stock injector/stock cp3 trucks make 500-525 all the time and do it for ages on a hot tune.

What is most power I can make on a hot tune with only a turbo and built trans? Like a 64mm turbo.

Depends on the health of the OEM fuel system. I've seen mid 500s-575 area pretty repeatable with a health OEM sized fuel system. Now if we're talking a 200k mile fuel system I doubt it'll get quite that high as the injector return rates will be bleeding off high pressure supply, the pump will have a higher return rate than one with say 50k miles.

IMO on a stock fuel system I don't like to count on anything over 525-550hp with a turbo upgrade. That way nobody gets their hopes up.

The triple stack of doom days were much better 🤣
I remember those days but always wondered how that actually worked. I thought those programmers would just load their maps thus overwriting the previous programmers maps. or did they read out the table and do a +100 or something and reload it back in?

foolers would be different and I guess can be stacked

You would run say the bully dog that flashed the ecm, then use the edge attitude because it was a pass thru, then I think it was the ppe duramaxer something that was a rail pressure fooler if I remember right

How could I forget the triple stack of doom?
that always made me think of those triple stack hard attack burgers

Mike L. once told me that the Banks tuner on a 5 speed made him tons and tons of money by slipping transmissions in short order; sometimes just a weekend. I asked about the ole stacker crowd and he laughed so hard that I had to just sit on the phone and wait for him to catch his breath! 😂

Ah the early days of tuning...I still have my old stock injector tunes from my lb7. 3150us and 32 degrees timing....we wonder why we were bending rods and killing pistons at 500hp 🤷🏻‍♂️

After the canned tuners came the “all red” tunes. The tuna man hated when I’d ask him for those . Man I remember the guys who took “all red” seriously too

Anyhow, the old 3200, 32* tubes could be rod benders or piston crackers. Depends on the day your truck was built. It bent my rods with twins lol.




Now the goal is no more than 1500-1600uS (point of deminished returns), more air than fuel but not enough that she’s laggy beyond what you want, enough cp3 to keep rail up and a tuner than knows how to keep rods in the block. Since all of this, stock engines have last waaaaaay longer and are pushing more and more power down the track.

The guys running stock turbo/injector trucks hot are still running those 3200/30 tunes and they seem to hold up fine. I agree less fuel and more air is far better but it's still done every day! That same tune with just a drop in turbo will usually top 600 easily though so it's far from efficient and kinda spicy lol.
