Hello.

I have been driving with an alphaspeed tune for a couple months now and loved it. I recently installed an o2 housing, and since I opted to not turn off the o2 sensor cel the first time, I now have a check engine light. While I do understand that this is normal. I was advised that I can still drive the car with full boost regardless of the cel. The reason they mentioned for this is that when I got the canned tune the first time they adjusted the afr to compensate for having an aftermarket o2 housing or not having one. They further mentioned that the retune I would get would just turn off the cel and they wouldn’t be changing the afr etc (I also had a downpipe and test pipe installed after). This does not make too much sense to me and was wondering if someone can help explain.

Hey does anyone know if LightExcel is still an active business? I’ve ordered eagle eye taillights for my coupe but since checking their social media, it seems that they were last active in 2025.

Hi. I got my car tuned about a month prior by Alphaspeed (canned go tune). I since realized - I should probably do the o2 housing. Do I need to get retuned to make sure I am accounting for the extra flow or will it be okay.
