Did you turn the truck up and try and make any fast passes?

Nah it's only on a 2600 us tune. I have a big 2900 is tune but would be worried about my motor the whole time. At 2600 us I can beat on i and still not be thinking "when is the motor going to blow". Fastest pass in the truck was 13.354. Now that I understand how to bracket race, I wish I would have raced on my tow or economy tune so if I had a terribly 60' I could switch to a bigger tune to stay in front.

With your mods I would expect you to be easy mid 12's. I ran a 12.6 @107 at rmr last year in my lb7. I had a built trans, lift pump, 2800 pulse tune and 64mm charger.

Nothing wrong with your slips that I see other than an inconsistent launch (60' times). ET never starts until you leave the beams, that's normal. If you get to do any qualifying passes just pick an RPM or boost level to launch at that you know you won't spin too much and can repeat. If you don't get any qual passes do the same thing anyway, just pick something. Don't worry about going as quick as you can. In my opinion, trying to kill it off the line every time is recipe for disaster for bracket racing. In my LMM I just put the tach at 2k rpm and let it go. Easy to see, easy to repeat, and very consistent.

Best three passes for me using that technique that I remember resulted in 12.613, 12.612, 12.611 back to back to back. Truck would run high 12.4x if I hit it harder. Who cares though, you're there to win.

I hate bracket racing! However I respect people that our good at it.
Do what jerry said^^^^^^^ and learn tge tree.

I hate bracket racing but if you want to win load your stock tune and pick an RPM to leave at. Who gives a shit if you run 15s as long as you can do it repeatedly. Almost every event I've ever been to has had a slow/stockish vehicle win the brackets.

Every event either Verlon or Rony win:D they can cut a tree!

Yes but that was with your truck stripped correct? What was your 60'? And mph? I'm running full weight and getting a very consistent 98-99 mph. Next races it'll be lighter :)

I ran 13.37 was my best ever full weight with a 24* timing and 2700us tune. Turned it up to 29* and 3200us and ran 12.75-12.8. My weight was around 7200-7400 depending on full. I wouldn't worry about turning it up a bit more. I pushed mine hard and to its limits.

Who's tuning did you have? If it's not the same as mine then we don't need to keep questioning the hp or tuner. It's obviously the elevation that is keeping 12 second trucks in the 13's haha. I mean at sealevel stock trans trucks run 12's! Plus rmr's track prep is very crappy. I'm happy where it is for now, until I can support a build I don't want to be breaking my daily driver.

That was with no back seat, tailgate, and a roll pan in the rear. Full weight the year before I ran a 13.0@103mph My 60's were anywhere from 1.6-1.8 depending on track prep. RMR's track prep is not great at all.

I'm sure it's corrected numbers for elevation. 5000' gives you a significant correction number.

Everything is under powered at this elevation. It's da is 7100, track prep sucks at RMR, a 2600 pulse tune should be around 550 hp anywhere. I made 596 on a 2900 pulse tune, and mike diesel just made 604 with 30% over sticks and he was running out of fuel from his cp3 with Lbz regulator so my numbers seem accurate judging on where his cp3 is limiting him.

I ran a 13.05 on a 2600 us and full weight with 3/4 tank of fuel, if I go to bigger tune its slower cause of rail pressure. New cp3 and get rid of robs tunes and it will be a easy 12.
