Not necessarily. Tons of Subaru and mitsu guys swap out to bigger turbos and bigger DP's and there is no need for a retune.

Yes, a rich AFR, is better than a blown motor, but there is something to say as "to safe" and sacrificing some easy whp.

uhh of course those cars don't need a retune there ECU's are Made to respond to boost,,, they "retune" them selves... it's not until you do major modes you need to start giving more attention to the tune and at that point it's almost standalone time,,,

and it's true optimal AFR=optimal HP... an 10 is SUPER RICH I must admit!
