Over the last few months I've done a bunch of stuff to my Z, bringing it to a kinda stg 5 depending on who you ask. Anyway, at this point my low end has disappeared, but I'm quite a bit faster mid and top end. Is this normal? I expected some loss with my lighter JUN flywheel and UD pulley, but nothing this drastic. I seem to have very little power in 1st gear, unless I go WOT and then I get a little spike of power around 5K RPM and then almost immediately I have to shift into 2nd to maintain the power. This gives it an almost VTEC feel that I'm not thrilled with. From 3K rpm in 2nd and on everything is great. Is this normal?
