Hi guys...i tried to pul the timing and fuel maps as it is on this threat....but nothing happen....do we have to have the sas valve or not????.....

 

 

I've found that the -20 ign will increase maf Hz on overrun thereby definitely meaning the shaft speed is higher. It 100% does work with out the sas. Also with sas keeps even more Hz airflow . Sas does not build boost in the intake mani, it builds shaft speed. Reducing spool time even in most cases in small amounts( just adding some to your post)

 

... I can't imagine this being a good, legitimate thing for your car.
