[QUOTE="HPLouis, post: 16216104, member: 5445"] Now I just came back from the dyno a couple of weeks ago: [URL]https://www.svtperformance.com/threads/just-came-from-dyno-with-questions-about-my-a-f-ratio.1175083/[/URL] This time, I have the 3.1 pulley. It only made 403 rwhp and it's still pegging the injectors and pump. Now, it still had the stock air box and silencer but 20 degrees of timing and it made 11.76lbs of boost. The torque was right there at 433 but no power and I read that for the Terminators, torque is usually within 6-10% of the range of power. I've been reading, searching on here and the FB forums and I see people getting up to 450rwhp on the stock fuel system and 2.93 pullies. I'm guessing that there's something wrong with my fuel system. I should be making more power and I shouldn't be maxing out the injectors and the fuel pump. I changed the fuel filter and there are no codes. The car idles and drives well. I can't figure it out and I wanted to ask the group here before I take it to a shop and have them diagnose it. Thanks [/QUOTE]
