flash Posted December 25, 2003 Share Posted December 25, 2003 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.

Chris Wilson Posted December 25, 2003 Share Posted December 25, 2003 The only cost effective means of grabbing a bit more power from the N/A MKIV is to remove both cats and fit a free flow exhaust system. I now make and sell N/A cat pipes, e-mail me direct (PLEASE, do not PM me...) and i can give details and prices. Beyond that the cost of worthwhile performance gains rapidly becomes stratosperheric, and it would be far better to change the whole car for a TT or whatever. I would suggest the "chip" is not at all a cost effective mod. Nor are "free flow" air filters, you may very well lose power by going that route. The stock system is a well engineered and totally none restrictive set up, leave it alone Link to comment Share on other sites More sharing options...
