I have a 98 24v 5.9L diesel. I have a cfm+ intake manifold and an afe intake stage 2 and a superchip right now. 4" MBRB turbo back on the way. I want a different chip just cant decide which one to go with. My tranny is stock and I would like to keep it that way. My speedo needs to be adjusted because I have 35's too.

 

First of all welcome to the site If you want to keep your tranny stock, leave it alone. If you want the best chip/box out there right now, get the Quadzilla Adrenaline with the Pulse control module, then you will have tire calibration. The Adrenaline will however cause a stock trans to run for the hills

 

For pretty safe drive ability, get a Smarty.

 

I'd recommend a trusty TST, believe it or not. Why?

-- Over time it has PROVEN to be the most reliable box on the market, in general
-- The Adrenaline is the most power, and versatile-- but is unproven in durability, and we have reports both of them melting down and of Quad giving good customer support.
-- The Smarty is to me a little expensive for ~40hp and a tire calibrator. Perhaps future Smarty softwares would change the value aspect-- if they ever come

With a stock tranny a XZT+ and a little self control might be the best.

But if your going all out eventually just go with the adrenline and save yourselfsome money in the long run but expect to be replacing your tranny or clutch pretty quick.

Fill out your sgniture so we know what you got. especially for this i think we are all asuming you have an auto.

Watch out the power is addictive.

 

You are correct auto tranny.
