Holy jumping Geezus you have to be kidding me. :spit: Im curious if your tune was made to bring power in at higher or lower rpm? I still believe its all in how the tune brings in the power.


Paint, I wish I knew why your truck didnt run like you expect it to.

After this past season of running a 3.0 charger with big sticks and dual fuelers I would have thought for sure I bent the rods. Well I finally got around to doing a compression test today.

Here's the results

#1 -390
#3 -380
#5 -375
#7 -365

#2 -380
#4 -390
#6 -365
#8 -365

Seems 6,7,8 might be on there way but still seems fine in my book.

I have had mostly Johnboy tuning in the truck since day 1 and they have always been built around sledpulling. My goal has always been high rpmand big singles. I have several things up my sleeve for the off season to help with that goal.

My truck never did well drag racing though. My best times were 12.70@107 but that was with a S465 and nothing else. The way the truck runs now it has 11's in it. I just have more fun playing in the dirt:thumb:

Given I dont race or pull alot,I definitely think sled pulling is alot easier on the motors. The few pulls I have done I have no problem holding it to the mat. At the track I almost always feel like somethings ready to let go.
