[QUOTE="Mattstang04, post: 15390020, member: 157575"] Just a little closure to this whole ordeal. Are longtubes worth the hassle? Took the car to the dyno today. It was 94 degrees F with 49% humidity. I have no baseline for the car in stock form. My only performance mods are the Mac longtubes and an offroad pipe. No CAI, no catback, stock 3.55 gears, not even a K and N filter (still got a motorcraft paper filter in it). I did remove the big rubber silencer from inside the filter housing. It is bone stock other than the longtubes and the mid pipe. Baseline with the longtubes without any tune changes was 304 rwhp and 312 tq. The mixture was rich averaging 12.1 air to 1 fuel. After the proper adjustments were made the car made 312 rwhp and 326 tq. The mixture is averaging 12.9 to 1. I am pleased with the numbers. I would probably recommend these to a friend. The price of the Macs were right and the payoff seems worthwhile. The job was time consuming. I'm not going to brag that I did it in a weekend. It took a solid 24 hours of my time and about 3 hours of a friends time, helping me out. I came incredibly close to deleting the EGR but with his assistance we found a method for getting it hooked up and happy. I did the job without air tools or a lift. Jacks, jackstands, back to the concrete. In all honesty it was laborious not complicated (except the EGR which was both laborious and complicated). But hey I made over 300 to the wheels with my first performance mods on this car. That's a good deal.:beer: [/QUOTE]
