i know this has been discussed many times before, but almost all the replies seem to relate to twin turbo supes. What are the best tuning upgrades for a N/A . Also i've seen a lot of talk about not being able to chip Supras, but "Superchips" are advertising a chip for a N/A for about £300. Anyone on here got one/ had one or know anything about them/ are they worth fitting. Forgive my ignorance, but all help is appreciated. Ian.

sorry guys , but those look absolutely shocking.

i've just sold my scooby and bought a much longed for supra it's an imported non-turbo auto. i don't have an owners manual, so i've got a couple of stupid questions to ask you good people. 1. what does overdrive do./ what's it for ? 2. the red button next to auto gear selector. what's it for ? 3. another button next to gear selector, marked "manu" and "ect-s". what's it for ? all comments appreciated.
