I've had my home made setup running for about three months solid now at 10lbs. No problems, still needs a little bit of fine tuning on a dyno. One thing I've noticed is that when the motor is warmed up I get some bogging under vacuum. No problem whatsoever under boost or while the motor is cool. It only seems to happen when the motor is good and warm. Any ideas? I did replace the plugs with one step colder plugs, but had noticed the same thing even while I still had the stock plugs in.

 

Where is closed loop setup at on your map?

 

How do I tell? I know where the open loop setting is. It's actually a map you had sent me a while back. I'll send it to you again if you want.

 

try getting a new catylitic converter

 

No cat, test pipe instead
