Just getting the new set up out for the first few rips and sometimes when I pin it it will go to 7000 rpms and just sop there and if I let off and hit it again it goes the rest of the way just fine. Any ideas where to start first ?

Mine is not etec, but w/ those symptoms, I'm guessing powervalve. Make sure lines are all routed correctly, might have blown one off. Bottom will be fine and then struggle w/ upper rpm.

Does it sound like its just falling off or does it sound gurgly like its rich bogging out?

I couldn't find any part of the rave system disconnected. I was going to pull my clutch but noticed I forgot to turn the clickers down they were on 5. And when I was test running it was at night at my new house where I am not familiar with anything yet so I didn't have good long pulls or anything where I could watch closely at my rpms I wonder if I over revved and it cut me off to 7000 ? Is that possible?

you very well may have been in over rev but if you rehit it and it revved as you imply then its not over revving. check that boost it box well, they still have issues and your is doing one of the things the offending boxes did..

I always forget about etecs pulling rpm if revving to quickly. Hopefully that's your problem.

The clickers made a big difference! But from a dead stop to wide open it still stops at 7000 and if I hold it it will eventually go like normal. I get what a bog would be like but this is like nearly normal till 7000 rpms then bogs

Check your fuel settings. I think you are over fueling and the engine is not able to burn off all the fuel quickly. If you were running out of fuel it would just lose power.

Brandon at tss basically told me I would NOT have to adjust anything but boost when I ran different fuel.

Keep an eye on your air fuel at 7000 rpm. If its in the 12 to 13:1 range than its not fueling. If its not fueling take a peak at your secondary rollers and make sure you didnt crush one. If thats good you need to pull your primary apart and look for something broken. It really sounds like symptoms I had when I crushed the secondary rollers.

good luck

Doesn't sound like a coil problem, but the 2013 was known to have coil problemes. Might be worth swaping some out to eliminate that.

I really think Nick hit it on the head. the shift is stalling and unloading the engine. betcha he has 3 sided rollers or at least one that has been unrounded..

alsways start troubleshooting with the basics/easiest things to check. look at ur primary clutch first for this symptom. worn ramps will definately do this if theres any bumps worn into the ramps. if they arnt smooth then replace them. also freeplay in rollers. 90% of problems have easy fixes. sorry if u already checked this

The etech computer does not like the upshift to happen to quickly it is a matter of adjusting the clutch set up to slow down the up shift
