HOLY CRAP!
You telling me your 400hp time attack car will pass OBDII scans!
and for the record, my F/IC does have some stumbling issues now and then, but I'm satisfied with is as a daily driver...and it also passes OBDII.

some think their partial throttle tune is perfect but its because part of it is most likely the open loop part of the part throttle.. or push the throttle too open to get out of closed loop.. at certain point while doing partial throttling their is a leaned part that some dont notice because usually while boosting you keep pushing more the throttle to keep on boost and then eventually goes out of closed loop fast, but I bet very use PT steadily.. and many love WOT more than PT..
without anything to tune the closed loop, you can still do partial throttle, just a lil practice to stay on the open loop part

man, so the things that happens with my car is normal?
i'm having crazy problems with my factory ecu taking over the fuel trims, it's bringing my afr's down to 10 at idle and 12~ cruising, bassically it's redoing the whole partial throttle part...the only reason i realize this is because it leans itself out after i give it a little more throttle, pushing the load a little higher on the car (which is somehting i don't ussually do, i drive like a granny)
what i'm trying to say is that, with the adaptive ecu, it learned the range that i drive( which is slow and with lower loads) and modified the tune to TRY and achieve the better afr's, thus making me run rich...right?
i'm just trying to understand this.
can i remedy this by unplugging hte o2 sensor? arizona doens't have emissions laws until your car is at least 5 years old haha

great page 4. im going to probably have to reread it like 26 more times to understand but i certainly learned a thing or two and i will spend the extra money for a quality product next time i buy an aftermarket part.
thank you ptuning and dezod.

The higher the hp, the more restrictive a 2.5" exhaust becomes and the more noticable the gain will be with a larger exhaust.

Not always. I remember you speaking those words on occasion.
