Just because you limit the boost to 10 psi doesn't mean that you aren't running lean. You can have more airflow at the same boost level with a free flowing intake and exhaust. Put a wideband on the car. Its the only way to know for sure.

 

the midpipe will just sit in my house until i buy a PFC, it's all good no rush to just throw it on im not exactly a "hey lets all stare at my car" guy, when i go to hang out with my friends in a parking lot i've always parked any of my cars away from the crowds, the poeple who know me know what i drive, no need to walk around/drive around announcing it lol. (although right now my durango is shiat, it used to be relatively hooked up, and my jeep before that was an attention getter, which is why i got rid of it.)

note that factory ecu runs slightly rich to begin with..

recall someone proved this with a wideband..

recommend fuel control as well with midpipe...

 

yup i'm goin back to my original plan of modding, ECU comes before anything that changes important factory ****, such as the cat.

cam at pettit says that they RETUNE their ECU's for the mods at roughly a 10.5 air fuel ratio-the same number that the stock ecu runs, proof that there is a little leeway there as far as the richness is concerned....just a thought....

 

Isn't boost creep with a midpipe with a stock wastegate a problem?

 

we used to call midpipes the apex seal removal tool
