I read the performance list mods up above and I found a throttle body by Napa and going to call about 4.10 gearing. Would it be wise to go with them or with keeping by al? I bought some stuff from Napa in the past but nothing like this

Throttle body wise I would only go with fastman. I went with him and the process was great and the product was even better. Plan on doing the same for my WJ.
