Hi all, I have posted 2 previous threads regarding QG16DE modifications but sad to say, no one replied to my thread. But anyway, I am already did the I/H/E setup on my QG16DE namely AEM CAI, 4-2-1 extractor with 2" downpipe setup. The catalytic convertor was also removed and the stock centre and rear mufflers are replaced with 2" free flow mufflers. I am also using the Unorthodox crankshaft pulley. But however my low end seems to be very laggy and the power will only comes in after the 4k rpm zone. I have tried advancing my ignition timing with a CONSULT but it doesn't seems to improve alot. Is there any other ways I can do to improve my low end? I will greatly appreciate if someone can enlighten me. Thanks in advance!
