Hey guys my names Kenny I recently joined the forums from constantly looking things up about my stang and found some really good helpful info on here. My question for you guys on here what mods should I look for to get the best bang for your buck/ real hp gains on my 1999 Ford Mustang GT?? Right now its purely stock besides a BBK CAI and I'm the second owner of the car bought it from a guy that got the car from an auction. Did a carfax on the car as well it had a laundry list of upgrades to the car just the normal wear and tear of parts that have been replaced by a reputable place. I do have some knowledge by reading on here about getting gears 3.73, an exhaust, etc. Anybody with the same type of car that can give me some advice would be great. Thanks for reading!
