Boost limited to 18psi, whacky AFR, no codes
2008 LNF 76k miles
Catless DP, muffler delete, k&n cai, forge bpv with a Trifecta Custom tune.
I just got back from the drag strip and noticed I was peaking at 18psi. I used to do 25psi. My first thought was a boost leak, but I just had the front of the car off when I put in a ZZP radiator, and I didn't see any cracks or anything on the piping or intercooler ends.
Another interesting thing I saw was my AFR shot up to 30 for a second under wot. Obviously bad, but I haven't been able to recreate this again, so I don't know if it was just an anomaly.
I have no codes or anything. Car drives fine other than not pulling like it used to.
Any ideas?
