Why are you running at 9lb's you can atleast turn it up to 18 psi. When I first got my s14 with a stock s15 engine street tires I did a 13.4 at 18psi.

Im running a t3t4 50 trim turbo. On 9psi I can't run any higher till i get a tune. it took u 18psi to run a 13.4 It took me 9psi and i ran 13.5. I ran half ur boost and got a tenth slower. Once I get my tune I'll up my boost. my a/f is at 11.5 under woot once I hit higher rpms it goes to 12.5 so 9psi 13.5 that's really good.
