If I don't find anyone to install gears for me soon I'm going to order the tuner in the next week or soSince you have an automatic I say definetly. I highly reccomend getting an sct tuner from americanmuscle.com and you get free tunes for life. I had a diablosport and sold it for my sct and it was well worth it. They send you tunes specifically for your car. Gain much better shifting and you may only gain 15 hp but thats throughout the whole powerband. I also gained 2mpg on 87 street tune.
