Have you put it on the Dyno yet ?

 

I dyno'd it after the supercharger and Flowmaster exhaust system with a high flow CAT and headers and it was 480-ish....but i put some more upgrades after that like ecu chip tuner and cool air intake with a big filter.....i have to dyno it again to see its new max HP but id guess its in the 550 region

 

Wow very impressive #'s. Who distributes the PCM tuner ???

 

a friend of mine owns a shop and restoration place so he let me use his chasis dyno...he had an engine dyno too but i didnt feel like taking my whole engine outta my car just to see the HP produced at the flywheel.

 

Sorry, you must have misunderstood. You wrote the you had a ECU tuner (pcm) I am wondering who makes it for the HEMI ??

Thanks, great Truck

 

welcome dude, nice truck, have you ran it at the track yet??
