    2005 GTO Twin turbo

    Hi, I have a 2005 Pontiac GTO that I have installed an AVO twin turbo kit. I made the installation and the tuning in a garage were I live. The car drove great for the first couple of weeks. However I started having this problem recently and that is the car is cutting (hesetation) when the boost comes on. I have noticed that when I put new spark plugs on the problem disapear but comes again after 2-3 days. I thought the car is very rich but its not from the look of the spark plugs when I open them. Any suggestion would be appreciated

    disconnect the battery for 10min next time the car starts hesitating and see it the problem goes away. if it does your fuel trims could be effecting your boost afr once they learn

    Yikes.. One thing to note: you should populate your boost VE table all the way up to 255.. Just for safety..

    You turn on your fans at 217 and 228 (Low / High respectively) ... shouldn't you turn them on sooner?
