We @ JLP Just dyno'd a 2004 Lightning. were not finished yet. we will be finishing it tommorow for the customer to pick it up. We installed a 5# lower pulley & Our Forced Air kit..Thats it!With these 2 mods and our tune we were able to put the customer in the 400- 500 club!(411-537).. I'm sure they'll be happy when they get the dyno sheets!. We currently have 4 2004 Lightnings @ the shop to get similar mods..I must say i was impressed with the results myself..Give us a call if you have a 2004L we can do our rev. chips or the predator.......JL

Nice work Johnny

Boy, are those SRT truck owners really going to be crying if they run up on one of those bad boyz

 

Awesome numbers...

 

You clown, it clearly says on the dyno sheet STD! Oh yeah, my truck is faster then yours bro. -Mat-

 

Alright dumb question time... are the 04 motors any different than the 01-03?

If not then the same should be possible with any of the 01-03's right?

Great numbers... I'd like to play in that sandbox with my 01!

 

Hey Johnny, did you make a pull before mods? It would be interesting to see what you got out of the L stock. Maybe you could post up some stock dyno #'s. I've seen this question asked before, and since you have 4 trucks, maybe you could hook everybody up.
