I understand that both SPG9 and Sweedish Dynamics make essentially the same mods. The difference between the tweaked boxes (pots + resistors) and theirs, they say, is the programing of the chip, which affects the power curve and is more discriminating reg: knock sensing.
I tweaked my own, and boost improved somewhat, then put in a Sweedish Dynamics box and noticed (1) earlier boost, and (2) sustained boost, about 2/3 into Red with definite knock sensor response. SPG 9 is apparently similar, based on past discussions here.
BTW, adjusting the pressure cut-off for increased boost is fairly simple. Helps to have an accurate pressure guage.
