AEM ETI Intake w/ Invidia Test Pipe
 

So I installed Invidia test pipes on my car about 4 months ago(rediculously raspy) and after 2 days my check engine light came on. I bought the AEM ETI intakes for 125$!!! and after about 10 minutes of driving my check engine light went off and has stayed off. I was under the impression the ETI(electronically tuned intakes) would do nothing along the lines of tuning my car so im curious as to what may have happened to have the light go out

Well from my understanding, intakes lean our cars out so the o2 may just barely be passing to make the light go off.

Okay so would you expect my baseline dyno run to actually show hp gains before my tune?

You still have your OEM exhaust installed?

I have test pipes and short tails
