Sorry for my lack of respons, I really appreciate the answers on my question though.
Still haven´t decided on how to proceed with the MAF..
If I´m not totally wrong: People seem to be happy with the 74mm throttle (also IPD is designed to fit with 74), the OEM MAF for the 986s has an inside diameter of 76mm so are there really any reason to go bigger on the MAF? Using a bigger MAF that will need some sort of recalibration will add complexity and I´m afraid it will increase the cost for my tuner. (it´s expensive enough anyway)
Then I look at the Anniversary model, as we all know it runs on a 987 airbox, I just realised that is also uses the 98760612500 MAF. Could that be an option? If I just use the 98760612500, will I then not need to recalibrate the ECU for the oversized MAF?
Sorry for all the questions, I´m such an amateur
