Ok first of all I apologize if this has been answered somewhere and my search skills suck. I feel like this topic has been beat to death in a way but I have not found a good answer. I have a 13 Speed3 that is in need of a turbo, still on the stock K04 @139,000 Miles! Car is using oil and plugs show no signs of oil fouling. Compression is 185-190 across all cylinders, PCV valve is a year old and was done when I did my valve clean. I initially was going to just do a BNR S1 as I am not tuned and don't plan to until next spring. I am still on the stock HPFP and will do Corksport internals and the rebuild kit when I install the new turbo. I bought the car used in 14 with 13,000 miles and the original owner had installed a Corksport intake. I have never had an problems with the car and it runs great other than oil use as of late. The only other mod is a cat back but I am still on the stock DP and midpipe. My question for everyone is can I safely run the S2 on the stock tune with a HPFP upgrade? My goals for a tune would just be to optimize everything and stay conservative and hopefully pick up some safe HP. This car is my DD and I want to keep it around for quite some time as I am very happy with the car and honestly enjoy taking care of it and replacing parts as needed.
