5. In the future if i fit after market headers and exhaust how will the new ECU manage
It's always worth doing a dyno run to check the AFR when you do extensive breathing mods though.
The J's ECU can be a bit different, as they are often much more custom. ie when you order one from J's, you tell them what mods you have and what fuel you use, and they select one of many pre mapped programmes to load onto the ECU.
TBH there isn't a lot of scope for adjustment between differnet breathing mods, so I think it's not that relevant, and not mucj will be gained or lost.
