I have been trying to get my RPMs right for my TD Max 16sm tune using my new Dalton weights (plan to keep everything other than weights stock). I set them where suggested by TD and went to the ice to get a decent pull. I saw 8700/8750 most of the time. TD says that's a touch low, so I pulled out 1.4 grams, and tried again (they suggest aim for 8950/9000).

This time I spent a few minutes understanding how to actually use my gauge cluster for the max RPM recall (knew it was there, didn't know how to check it). Back on the same ice I visually see I am pulling about 8800 RPMs now, not much difference. That's from about 25mph all the way through 90mph. Fairly consistent.

The troubling thing is when I do a max recall, I see 9385/9413 RPM from the gauge.

I realize that the gauge reads the absolute highest value it sees, but for #*$&@'s sake, that seems kinda high (got to be approaching rev limit). So what do I do? Do I put back in the 1.4grams and see what the max recall is then, or do I ignore this high value? I know you are really suppose to base clutching off of readings you are seeing, but I can't figure out where these super high RPMs are coming from.

I don't recall hitting the rev limiter, but should I ignore the lower rpm values in favor of the max recall, or vice versa?

Thoughts?
 

My 2 cents... I don't pay attention to the recall. Find a stretch where you know you have good traction and do a few pulls and safely try to keep an eyeball on your rpm.
 
Your spinning off the bottom and the MAX rpm picks it up.
 
My max says 9550 talked with thunder not an issue unless it stays there. Most likely a quick spin of the track. I'm still breaking in (180 miles) when i look at my gauge at wot I'm around 8750. Give it a few more miles and I should be perfect 8950-9000
 
Guage is slow reading unless on a very long run. Recall is dead nuts accurate. I don’t know about you but I clutch my sled assuming it will spin. Still should not hit limiter. Don’t forget that’s a soft limiter. When you feel or hear it it has already been activated and cutting power.
