Well I went to a local tuner to gets the rams speedometer calibrated right. He put it on a dyno as this was easier to do rather then running it down the interstate.

After he dialed in the speedometer and shift points I had to ask if he was going to make a dyno run.(I didn't plan on this)

He said he was wanting to anyway since this truck has so many different parts 1998 ls1, 2001 computer, aftermarket fuel pump, headers, ??? MAF meter..etc.

First pull he let out due to it being lean..still ran up to 300hp 330 ft.lbs. I have been running this truck for a full year now so I was surprised I never heard any spark knock.

He added some fual and made another pull....

With A/F more dialed in it made 315hp and 349 ft.lbs. The graph loked great all the way til 6300.

On the drive home I had to make a full pull and I gotta say it feels alot better between 5500 and 6200 where it was very lean and now my 2-3 shift kicks good vs hitting the rev limiter....13's here I come!!!

 

Sweet!! I still love the fact that you put that motor in a Dodge!!
