Want to build costom turbo kit. Need advice from boosted guys! - Toyota Yaris Forums

pimp my yaris · 03-22-2012, 09:22 AM

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.
