Thank you all for the in put and kbracing,i think that's what my tuner was trying to explain to me if it helps I bought the truck off of the forum it was for sale and posted in Feb it's a 2001 with built 5.3 from the kansas area the tan colored one.I'll see if I can post the link to it here. I guess this is what I get for just buying a turbo truck instead of building my own lol. Seemed like a great platform to build from.

Hope this works. This is what I'm working with.

You talk about 600rwhp like its a waste of time

Haha no this is definitely the fastest vehicle I've owned so far couldn't be happier with it. Im just anxious to get this thing to 800whp is my goal. Will be taking it to the track July 10th in Topeka KS for street car takeover.

In my opinion, 600whp is about the sweet spot with these trucks for daily driver or mostly street status. Its pretty easy to control at that level and also very fast. After more power traction gets harder and harder and things get more tempermental. Just my experience anyway. Good luck!

Yea it seems like it...also the guys who tuned it said it should make more on street because my converter too loose for dyno what are ur inputs on that?

It will be faster on the street than the dyno would say. Converters are picky things. Being able to lock them on the dyno eliminates that which is why a lot of tuners do that, but is a bad idea on a heavy truck in my opinion. No need to lock the converter if it is doing its job properly. If you log engine rpm and trans input speed it will tell you how good your converter is doing. You want <10% slip at peak power RPM. A bad converter will be >20% and will be wasting a lot of power and putting a lot of heat into the fluid.

George C....

Actually you want less then 10%
Target is 3-6% slip but cheap converters won't ever work as well as high dollar ones


As for locking a converter it has it's advantage in a lot of setups...some factory boosted vehicles lock as soon as they click into 2nd

Yea I said good ones are less than 10%. 8-10% is generally considered the max you want or what you can tolerate before the converter should be tuned up. But this brings me to my next point, what race teams shoot for and what works good enough for the typical DYI road warrior are different things. I have no doubt some boosted setups lock the converter, I just its a bad idea on a heavy truck in my opinion. That doesnt mean people dont do it.

I see thank you very much for input I'm curious to how much slip it was when it was dynoed.
