Greeting. I would like an American market Evo 8 GSR. with evo9 turbo and evo9 pistons, new walbro 255 ac pump, new 2" stainless exhaust all the way. Factory injectors. Factory 4-connector engine controller. I just installed an AEM Uego wide-band lambda probe. I would be interested to know what this config can do permanently?

 

Search in the dyno results section for evo 9 turbo results.
Here is a link to the first result I found but there are a bunch. https://www.evolutionm.net/forums/ev...urbo-93-a.html
In your specific case, the stock injectors and boost controller are going to be your limiting factor I think. I'll also assume you meant 3" exhaust lol
