I have been lurking around long enough to learn that i don't know anything about tuning. I don't want to change anything on someone else's Truck just mine. I'm a nuts and bolts guy but feel like I can learn this. Where do I need to start buying and as far as credits how much do I need to buy.? My truck is a great truck but it shifts awful and very inconsistent. I have read most everything in the Toyota section of this HP Tuners forum and don't have a clue where to start exactly. I hope to fix a couple issues without worrying the hell out of everybody. I live in the Middle TN area and there is a lot of people around who are happy to make your money disappear but don't fix anything. Any advice or help is appreciated. Sunfish
