Default Shift rpm

What rpm are you guys shifting?

1>2_____rpm
2>3_____rpm
3>4_____rpm

If you don't mind, could you fill this out?

I need some help understanding, the "whys" also. Mainly the 2-3 & 3-4

On my stock 29" tall Firestones and N/A setup I was:

1>2:6400rpm
2>3:6700rpm ... This was to keep me in 2nd gear through the traps
3>4:6000rpm

3>4 didn't really matter to me as I never really wound out 3rd gear. LOL

I'd hate to be wrong, but I think he was using that Comp 226.

Quite a bit of duration. So its possible that it made power that high.

Nah, that was with my 226cam. It pulled flat to 6700rpm NP, I would lose TQ but the truck went faster staying in 2nd gear than it would shifting into 3rd even though I had more TQ. Weird how that works due to gearing.

This is the dyno sheet before tuning

I can't gain rpm for **** in 3rd gear. It'll gain mph, but it'll sit there at 4k rpms forever
