[QUOTE="Ryan, post: 10799900, member: 303"] From what I've gathered if you go turbo back and no tune you will actually loose some fuel mileage. Going with a tune won't make the truck illegal. I don't believe the cat is going to be overly restrictive. It does neck the exhaust down to 3" IIRC, on a 4" exhaust at this phase, but then opens back up to 4". My buddy just put a cat delete pipe on his truck, and when we looked through the cat you could still see through it and his truck has something like 90K on it. I believe there are a few EGR delete/bypass kits out there. To be honest, I haven't looked into those too much as if I do I'll want to spend more money on the truck. Cleaning the EGR valve won't trip the CEL. However, I'd use MAF cleaner on it instead of CARB cleaner, the carb cleaner is a bit too strong for them from what've I've read. Something I need to do myself. BTW, you can get tunes for 'cheap.' I got my stuff for 200 bucks. $100 for a XCal2 and another 100 for tunes. Don't think you need to drop 400-600 bucks on it! [/QUOTE]
