Hey guys as some of you know I install LMS supercharger kit with meth kit from my buddy ELias.After some kms check VSC and check engine light came on.I have the stock exchast and my buddy Elias told me that i have to buy extenders for the O2 lamda.I install the extenders today but after some kms the check VCS and engine came back on.Can someone tell me what may that be?Is it the stock exchast that causing the problem?The car is running great by the way.The diagnostic showed O2 sensors right and left.I haven't done anything different than Elias did.Only I don't have an exchast.Should it be the problem?Any help would be appreciated guys

What are the exact codes that the car is throwing you. It is not uncommon that after you install some sort of forced induction system on a N/A car that you get a check engine line from either MAF or o2 sensors. Generally what is happening is the car is either running too rich or too lean outside of its stock parameters. Usually the best course of action is to get the car tuned to adjust AFR when your WOT or regular driving.

Usually if you run 6lbs or less, you will be fine but anymore and it suggested to tune
