ok i just got my headers installed and got rid of the cat..now that my exhaust is done do you think its time for a AFPR? cars seems faster but if im running lean im sure thats killing WOT power let me know your .02 cents

 

yes, my car ran like s*** after headers until i upped the fp

 

i also had to put in a heated o2 sensor downstream

 

my car isnt running bad feels like i have a bunch more power i guess ill go ahead and make my FRP adjustable the next day im off work since im sure it might help

 

or probably make it slower. These cars come with rich WOT tuning from the factory. Your free flowing exhaust might have made it "just right" now. If you are going to tune you need to be able to know if its making any difference or not.. good or bad. Seat of the pants isnt worth jack either.

and with shorty headers i dont see why youd "need" a heated o2 sensor. Doesnt hurt though but not necessary

 

i needed it because the stock position of the o2 sensor is right outside the exhaust port in the stock manifold.........having it downstream by the y pipe causes the exhaust gases to be a little cooler.............i do know this after i installed the heated sensor from accell my check engine light went away......

 

i havent had a problem with that yet...i thought iheard our cars came lean from factory...anyways i am getting a code 32 (EGR) code now i think i must have damaged something during the pass side header install...lets just say i got fed up and things got forced SOTP definetly isnt a dyno but this is a major difference for me...cat may have been clogged used to barely spin now it does this
