P0234 + 3" turbo-back
Hi,i have evo 8 GSR 2005, few days ago I have instaled 3" turbo back exhaust, after that i felet more power in car, but some time at high rpms it was fuel cuting, then i instaled boost gouge and saw huge overboost at 2nd gear about 1.65-1.7...i think its to much...and then i saw CEL light and P0234 error...why it hapened?
there is two reasons:
1) new exhaust
2)rear O2 sensor,couse i instaled i t like there https://www.evolutionm.net/forums/sh...d.php?t=114931
is it boost to high? can i fix it with remaping or with westgate actuator?
thanks, i am waiting for response...
