Do i need to retune ? .. increasing CR

Currently tuned on the 9.3:1 CR setup.
Going from 9.3:1 -to- 10:1 CR .. do I need a retune ?
Will engine still run reliably without a retune ?

yes you need a new tune. anytime you up the compression you will have to have a retune. I would not even take a chance on this one.

Note:

Anytime you change the AFR (CR,cams,et..) you need a re-tune
