I wouldn't go WOT again on it until you do some scans. I cant believe you wouldnt have massive KR on that build. I have practically everything but heads on a genV build and I get KR blips occasionally when its this cold and before they Dyno tuned it I hit 6 KR. GenVs are ridiculously efficient. I was getting 8-9 PSI of boost on a 3.25 pulley and 10-12.5 on a 3.1 pulley. Pretty big jump. You should stick with a 3.6 at the least. There is no reason to ever run 15.5 pounds of boost anyhow. 10-12 and then bump up the timing.
Also your gas milage is fine. Thats pretty much what people get when things are doing things right lol. I dont get anywhere close to that anymore.
