LTH = Installed, Review

If this is always the case then when someone installs a CBE and does not reset the ECU then what you are saying does not apply. Here is the bottom line. The ECU is constantly cycling and checking parameters. The theory on some of these new cars is the harder you drive it after the new mod, the faster the ECU will learn the new mod. Here is what it boils down to:

Test A: Dyno the car to get a baseline. Then bolt up a new exhaust system and intake system. Dyno the car immediately after. Do 2-3 runs on the dyno. The gains may be there or they may not. The ECU has had not time to adjust or correct. Do it the same way but now dyno run the car 6-8 times and you will see in that amount of pulls the ECU will start to adjust and now know the new mods. Your gains will be much more substantial.

Test B: Dyno the car and get a baseline. Then bolt up a new exhaust system and intake system. This time take it out and put some miles on the car. Usually 50-100 will work. Then come back in and do 2-3 dyno pulls. Now these dyno pullls should be higher than the first three from test A. Because you drove the car and put miles on it, you allowed for the ECU to learn and therefore should not need as many dyno pulls. But if you want, do a few more pulls for peace of mind.

Personally I do not like to disconnect the battery unless I am doing a major install like the headers or intake. If you disconnect it, it will take longer for the car to learn the new mods. I am not talking out of my hip on this one. I have done it with this car and seen the patterns...
