I just had my '03 Silverado 4x4, 5.3 dynoed. Bone stock it pulled 241 rwhp and 267 rwtq. I installed a K&N cold air kit and Gibson exhaust, and tuned it with truck edit. I came up with 264 rwhp and 298 rwtq. We firmed up the shifts and changed the shift points in the trans. What a difference over the stock setup. Can't wait to race my brothers '03 Hemi Ram.

 

Spank him.... Then do it again. Then let us know how it went.

 

Good numbers. Get that Hemi on the Dyno!

 

Yea .. lets see what the Hemi will lay down.

I wished ya'll wold have raced while you were bone stock, or did you? If you did who won and by how much?

 

My buddy just bought an '04 silverado. Same as mine. I took him by 3 full truck legnths up to 120 mph.

 

Wow... those are nice number..... At 20% drivetrain loss, looks like you are putting 300 hp at the crank. Did anyone ever told you these eingines are underrated?
