...ya bro..i admit that i am going no where using the shortcut method..thanks bro for reminding me..now i am heading to dead end despite all the other proper method i didnt think of..have to change course..hehe..but for piggy back, i have to go that route cos the stock ecu cant handle 450cc injectors, my mixture too rich during idle up to midrange..but under boost ok..because now i control fuel just using fpr..need extra fuel during boost but during idle also fuel will become rich..so i need something to trim the fuel during the early range..
but anyway..thanks bro for reminding me.
