The previous guy used it on his 2000 Gt, so this should work on my car right? Also with these hand tuners it says that it can:# Dual timing adjustment points (2000-4000 RPM / 4000-7000 RPM)# Timing table (+10% / -40%)# Dual fuel adjustment points (2000-4000 RPM / 4000-7000 RPM)# Fuel table (+40% / -15%)# Idle (+/- 20%)# Raise Speed Limiter# Rev Limiter# Cooling Fan ON/OFF Temperatures# Rear Oxygen sensor disable (use for off-road vehicles only)# Disable EGR (use for off-road vehicles only)#It can also Datalog for 90mins. The guy is including the Power AdapterPC Cable, Manual, and the tunerI know that not all cars are the same when it comes to the a/f and such, but whats a general good rule of thumb to use when it comes to advancing the timing? Also what benefits is there from diabling the EGR? I know what and EGR does, but not sure of the benefits or removing it.Sorry for such a long post. I just dont want to get it and not know how to use it. Tuning is my weak pt, but thats why i have u guys. ;D</blockquote>
