[QUOTE="Willie, post: 16034931, member: 14133"] I'm in line right behind you. Before I start, I'd like to make it absolutely clear that there is NOTHING that can be changed in the tune for performance gains. But there are several things that should be changed to maintain optimal operation for LT's (not shorties) >> 1) O2 Transport Delay Time should be increased, 2) Time Delay for Closed Loop for a properly heated O2 sensors, 3) Temp for Front HEGO to go Closed Loop is another change for properly heated sensors, and 4) Front O2 Heater Duty Cycle to use the built-in heater to our advantage. So I'm sure you're wondering why referenced tuner does not change these? My guess is because they do not have to be, and why take time changing stuff that takes time and therefore $$$ out of their pocket? I am a tuner, but actually purchased their tunes so I can analyze them (via datalogs). What I discovered, I believe, is typical of all tuners. And that is, you are NOT getting the best tune for YOUR car. That is a whole nother topic. [/QUOTE]
