Made A big move yesterday and cranked up the turbo to 12psi. Hade to make a competely new map for my FIC. Old map was only good to 10psi. Its was running VERY STRONG for about an hour of very hard driving. Then I noticed the AFR's were getting a little lean. I will do some retuning if possible. I may need more fuel system upgrades at this power level. Possibly new rail with a return line or even lager injectors? The good news is I am no longer using that jimmy rigged pull spring on my wastegate as my boost controller.

Before you continue do a compression test so we can see what it is before 12. Your rods are goona be the first thing to go. Careful you don't burn up the exhaust valves that can make it show lean sometimes. And Dyno that thing so you can brag about it
