MAtt everything on that engine is engineered to do a job.. All components DEPEND on all other components telling the TRUTH to the computer.
When you have a larger TB at any given position of the throttle the TB is allowing more AIR than the TPS is telling the computer... so in effect the mixture is ALWAYS too lean...so then the ox sensor or the clatter sensor tells the computer to make the mixture RICHER... And on and on.. Why mess with an engine that has had thousands...maybe millions of hours evgineering <img src="/forums/images/graemlins/pfft.gif" alt="" />to make it the very BEST it can be?
Save your money, time and effort and get some lower gears for more power.
