so my service engine soon light came on, and i check the digital tach thing to see if i can find anything out. i get the codes DT227, DTCNONE, DE6C090... i have looked up the trouble codes and cant find these listed anywhere. i do have cats... but i have an aftermarket Hpipe so im thinking that might be the problem??

try your mass air flow sensor if its running razzy. if not are your cats the stock ones or Highflow? are your O2 sensore lines posabbly on your exhaust or anything hot were it could have hurt them? maybe the O2 sensors are bad.

Is it one you can just turn off with the tuner?

[Ryno]

yup... but i had made my own o2 simulators and im thinkin a line might have gotten burnt, but the engine has not come on since we checked the codes... so maybe i can keep my fingers crossed

If you turn them off with the tuner you won't need them. I turned mine off with my predator and haven't had a engine light yet. I never put mil elimnators in.
