chip- take out that damn 108mph limiter
O/R H-pipe(no it doesn't run rich)
nittos
With the chip u can 4 mods in one(timing, shift points, a/f, and remove the speedo limiter) Plus taking the chip out defaults to factory settings too.
That would be a pretty quick land yacht if u ask me. U can keep the stock catback so it'll sound quiet. -Mark
