boost setup questions for mappers
 

Trying to reset the boost on my stocky wrx to

1. reduce highway fuel mileage on low throttle
2. reduce the on/off switch effect at very low throttle
3. increase boost modulation control at higher throttle openings

To achieve this (1) and (2), I have

A. Reduced wastegate duty at low throttle down to 0 at below 2400rpms
B. Reduced wastegate duty at low throttle at revs above 3600 to only 25%

To achieve (3) above, I have

C. Unflatten the Target Boost tables at higher revs against throttle position
eg at 4400rpms, against throttle position 12%-100%, it goes in absolute bar
maxxing out at 2.05 bar absolute being my target at WOT

2 Questions....

Any warning points to watch out for which I may have missed ? Should I rebuild the Wastegate duty for the higher rev ranges to be a gradual increase with respect throttle position ?

I know these are pretty long winded questions, wouldn't mind hearing some thoughts from mappers. Stock standard WRX MY04 Aus, no engine mods with exception of Apexi drop in panel filter

no one?
