Another S/C'd member worried about his AFR - Toyota Yaris Forums

Well I need to look for some 1zz fuel injectors now. I'll try those on, get some numbers, and then later, put the 1zz tb on that I have. Maybe they will equal eachother out?

You guys are doing some really great work at trying to figure out the lean condition. I'm sure there has to be 30 hp with a proper tune.
You would think the fuel pump can handle the volume of fuel needed to run 120hp, I think the problem must be somewhere else. it must be in the management, injectors, etc. I find it hard to believe that the car cannot compensate for a 20 hp increase. Has Blitz responded with anything?

Nope. I assure you that your HP will be lower with larger injectors, and the car will run bad off boost and when cold.
