would i need a tune

Yeah, 10:1 is way off. If that intake is making him run two points leaner than that, what's to say it's not two points leaner than the real stock AFR? That would be leaner than I would be comfortable with.

what is stock AFR then?

i was picking up 10:1 stock at WOT with torque pro for android and its getting that reading right off the ECU

If its higher than that that would mean im running too lean already and would either need a tune or to get rid of the intakes

should be in the 11.8- 12.5 range at full load that's the stock target, but we have seen them all over the place in real life

OK I never saw 11.8 at full load, always 10 stock, even after the ecu reset the dealer did when they changed my CSC it was 10:1, I started seeing the 12.7:1 after I threw on the intakes and reset the ECU

Any chance my app isn't giving me correct data? I don't have any other way to log AFRs so I don't know if torque is giving me wrong data or not, it shouldn't since its just pulling that data off the ECU
