I got a t-lok and 4.10's put in recently and the owner of the shop tuned my car for me. I had the tuner set to the basic "diablo tune" but he changed a few things for me. I know for a fact he changed the shift point to 5K rpm's. Everything else i checked and was fine, but the question is....is 5K rpm's a good shift point or should i set it higher/lower?

 

Well I would definitely set it higher than 5k. I'd say 5500 would be ok, but I'm always worried about valve float so I'm cautious.

 

anyone else?
