its a 1990 Twinturbo. i already have an intake and exhaust. i was thinking about buying the jwt chip but then my cousin said he is gonna sell me his afcs and avcr because he is getting a power fc. so i was wondering if i still need to get a chip if i just get the 2 controllers. i dont think i really need to raise the rev limiter and dont think im really ever gonna go past 150mph normally. so just wondering if i really need to shell out 500 more for a chip.
