2 THREADS?

REALLY?

 

Sorry I don't know what happen

 

Its highly likely that your chipped p28 does not have the correct tune for your setup.

 

Ill tell you what happened...you're a dumbass and made 2 threads

this

 

Don't make another thread.

 

there is no way you are using a b16 header on a b18c, the deck height of the b16 is shorter than the b18's, and does not fit properly...

i think you have more problems than running rich...
