I've been doing tons and tons of reading forum posts and pages about product reviews and still have questions. At first I thought that 42# injectors would be perfect, based on what people here said, but I've read several posts that have said it's just too much for the mods that I have. For reference I am purchasing a Kirban FPR and the car will be on a Dyno immediately after the S-trim is put on. Has anyone put a S-trim on and purchased a Power Pipe from AFM? What size is the pipe so I know what size to order my MAF. For those of you that didn't use a Power Pipe, what size MAF did you order and did you just need to purchase an install kit to make it fit/install/work after the Supercharger was installed? Finally, on my MAF order form at the bottom it asks if the car has the stock computer, which it does, but it also asks if the vehicle has a chip, and if so what was done to it? Now isn't a dyno tune supposed to be done with a MAF already on it? How am I supposed to tell them what's on the chip if I need the MAF for the tune itself? I've got a massive headache from all this, and if anyone can shed some light on these questions for me I would greatly appreciate it, thanks.
