I dynoed 11.3 which is apparently rich - if I use an AFC to bump me closer to the mid 14's does anyone know what sort of gains I can expect to see. Headers - Intake - Exhaust.

 

13.0-13.5 is what you want for NA.

14.7 under 3k/2500

 

12.5 should always be max power.

but if you're on a dyno, you can play with it and find out what works.

mid 14's at WOT on the dyno is too lean if you ask me....you should be shooting for 13 to 13.5 at WOT...you could possibly squeeze more whp if you go a little leaner than 13.5...but thats only if your gasoline permits you too

 

Our fuel's not as consistently good quality as in the US unfortunately - so it fluctuates between (US-spec) 91-93 octane.

See what the tuner can get me maxed power/torque.

Cheers for the input guys.
