I went a couple of weeks ago to get a dyno with a 150 shot. I left only making 371rwhp and 488rwtq? They drilled out what they thought would be about a 200 shot and my numbers didn't increase a whole lot. Strictly Performance then told me that I needed to get a 6AN line to replace my size 4. We put it on the dyno and it made 484/565 to the wheels! I was in shock. I gained 109rwhp by just replacing my line, lol. I really only wanted to make 425 and am actually thinking about going with a smaller size pill. Even though I have forged internals, this is my only means of transportation and I don't want to risk something breaking. I plan on getting a new car in a year and a half and if I end up spending too much on this one I might as well keep it. I haven't gotten on it yet but I can only imagine how nasty it'll be...
