Default Dv question

I have a 95 with the 175 pump. And I believe I just come across a set of 0.22 dvs outta a p pump that come off a garbage truck at work. With everything in my signature how much of a difference would they make. And I'm pretty sure there 0.22 cause stamped in them it says 0.22 and then on another part 927. Could someone help me out

they will be NUCLEAR HOT with a stock turbo. my .024's which are smaller they the .022's raised things 300+* even with the super B. i had to take a bunch of rack out of the pump to make things managable. your low end power will go up substantially but heat will be a major concern if you drive like i do or just use your truck as a truck. i wouldnt go any bigger than the .024's 181's 191's or .024's are more than enough in most cases. and how has your turbo not blown up with the wastegate plugged with as much fuel as you already have? there is no way your turbo will last. unplug the freakin wastegate, you have more than enough fuel to make 50psi without it plugged and blow it up like a real man.....

Truth fully I can stab. It through the gears never goes past 38 to 40 lbs and gets take all of a 100 mph in 5th gear to get close to 1100 to 1200degres. But I'm working on being the first in my town to have triples. But it's a slow process. But thank u for the much needed input appreciate it alot

With .022 on a stock turbo your pyro will climb faster than your boost gauge if you hammer on it. Kinda know from past experience.

Normal driving around was in the area of 700 to 900. Towing a 23 ft camper got to 1100 to 1200 last summer.

i think delivery valves should be the last part of the equation when you are putting a truck together piece by piece. if you dont have enough air -which you dont- look into some better supporting mods first.

I only put in .022 in at the time cause I got a good deal on them and had 370s with 181dvs and the 22s made it run smoother. I should have went with a 24 or 191 but couldnt pass up a good deal.

Never checked with the 370s. It was only about a month of the 22s than I put in the 5x.016. It went from around 20 to 17 than.
