John,
Thanks for the reply.
I am not talking about turbo boost controls. I am talking about the ROM (read only memory) that codes the Electronic Fuel Injection system. The computer controls the fuel and air mixture based on the data provided on the chip. These are never tuned to optimum (If this on is it will be the first one I have heard of). By adjusting the the tuning the memory to the optimum mixture you can improve proformance (5-15bhp) and you can even get better fuel economy. This is a very common practice. My ex. girlfriends father had all the ROM's in their BMW's replaced with tuned ones, including his M3 (which if any car should come with an optimally tuned ROM it should be an M3 or Audi S4 or similar proformance auto). Many people who race need thier ROM's tuned as a result of modifications to the engine.
Now in answer to your question about non-turbo buyers...in my case I simply prefer naturaly aspirated vehicles to turbo-charged or super-charged. There are lots of ways to modify such engines to deliver exceptional proformance, without subjecting them to the stresses associated with turbo. Don't misunderstand, I think turbos and super-chargers are a wonderful way of really maxing out power, a much safer way to go than nitrous. I am not looking for maximum power, I am just looking for a bit more to balance my non-turbo out. I didn't want a race car when I bought it. Had I been looking for one I would have kept my 1992 Jaguar XJS with its 5.3L V12 and modified it to 8L with dual super-chargers and power in excess of 1200bhp with torque in the same area.
Again thanks for you responce, and hopefully this will give you some insight.
Tootles.
