I agree in your last statement. I'm capping at 17psi since i tested higher and the car did not liket it. Actually with higher boosts I need to run richer and not Lead to avoid Knocking. BTW, the stock engine AFR went from 13.2 to 14.8)
Still lots to play and find the sweet spot on this car, it will require time and lots of analysis...maybe be going back to Map2 i guess ..will try these few days in map6 and see how i like it..

I'm not an expert in this areaq so I will send my logs to burger tunning and see ...here is a link that explains more of the rich vs lean http://www.turbobygarrett.com/turbob...g_rich_vs_lean

or this http://www.afrplus.com/AFRplus-unit-functionality.asp

Thanks will update the post if I get new direction from burger tunning
