Bogging under wot
Lately when I am in boost @ full throttle I am bogging (only @ wot). It started off as a faint bog and has gradually become worse. I am getting proper spark and fuel. Could It be my o2 going out?
Thanks

i have a similar problem... Just put my boost guage and air/fuel meter on.... problem... my fuel pressure regulator is at 48psi... and my car is running lean... also on my boost guage i'm getting 5 on vaccume... isnt it suppose to be on 17-20? i change the plugs to denso irdium also.. when i drive the car hard.. it bogs down at about 6k... basic setup on the car is a b16 with aem fuel rail.. and fpr... vafc.... garrett t25... vortech fmu... msd external fuel pump... i check the vaccume lines and it all looks good... i'm located in oceanside cali... near SD.... is there any shop where i can take it to.. so i can get it dyno tune...

Re: (p0gi)
This is hapening no matter where I put the plug gap and I have made no changes to my setup. It has always run and pulled like a gem up until this problem started and gradually has gotten worse. It has never thrown a CEL. Is it correct that the o2 couldn't be the problem (non existent @ wot)?

My friends does the same thing and he doesnt have the o2 sensor on(running open pipe). We are going to see of the o2 will help stop it from doing that @ wot. He has a crx with a d16a6 turbod by a greddy kit. Oh did I mention he has no FMU
