my 02 hd w/diablo chip and a 4lb lower pulley shifts at 5200 during wot.
i think it should be 5500-5600.please give me some
feedback.
thanks tony

 

I think that 5500-5600 is too high RPM for shifting....just my $.02
stick with 5200.........JR

 

mine shifted at 5200 stock, i am around 5500 ish now, which puts me a tad better in reguards to the power curve once its shifted. Depending on what your doing it may or may not make much differance.

Really 300 rpm isn't alot...

With my JDM chip my shifts around 5400 to 5500.
