Since there is a perfectly usable MAF system in place, I really don't understand why the need to change it. It doesn't stop people making big power and it's perfectly fine for tuning. All that is required is for me to implement the means of scaling the MAF so that it doesn't peg for those who need this.
As already mentioned previously, TT will be enhanced so that it does offer the option of significant standalone capabilties. So while there are certain limitations at the moment, in the future these will be addressed while still keeping all the advantages of the basic TT system.
