I've been working on my Moby 7 for a while now and the biggest upgrade I did was throwing a delorto Sha on it. The old gurtner was spitting gas and I could only get to about 23mph. The Sha brought me up to 28. Looking at the 3 different models released, it looks like I got the slowest rated to go only 20 mph. So I got my hands on a 15mm intake that I installed today hoping to see a difference from the stock 10mm. Low and behold I still top out at 28mph. What gives? I just want to hit 35mph to keep up with traffic. I guess I'm let down that this part didn't make a difference, advice?
