Car will just run pig rich after seeing boost. Do I need check valves with this setup? Someone told me check valves weren't necessary....

 

waht are your settings on the afc

 

They were about

1000 40%
2000 38%
3000 36%
4000 32%
5000 31%
6000 28%
6500up 26%

For high throttle.

 

https://www.homemadeturbo.com/forum/...;threadid=3347 your running too rich

 

i have the settings all the way down to -50% and the wideband still reads waaaay too rich. the car is getting a max of about 11psi on the T25

 

i read on a different thread that a t25 might be too small for a b18, maybe thats why u are running rich.

 

Are you adjusting based on boost at RPM levels via the boost gauge?

 

Not really, most ppl are telling me that -40% across the board should be fine and maybe richen it up to -35% after 5k RPM.

One question though, is the stock fuel pump and stock regulator fine for what I am doing here?
