Extractor: Tri-Y vs 4-1

[boyzone]

heard hotbit got good extractor..
mine just an old 93 mivec..no added management what so ever..just put this put that no tuning..im using those hytech replica selling almost everywhere in the net now..totally got diff from stock gti extractor i used before..but no dyno graph or figure to prove..in my car after install there no mivec feel after install just heard sound only in mivec engage..with gti extractor the mivec feel there la..rpm climb more happily maybe becouse of the size..but it only according to my butt dyno feel la..no management to tune..been slow with car mod now..

Not free only, and away from base ......hahhahahhaha

This is my previous dyno chart.
As per mentioned,
Run 1 is with stock ecu
Run 18 is e-manage with adj cam pulley.

Btw, observed torque dip at 4300rpm and still unable to recover by e-manage and adj cam pulley.
Suspected:
- is nature of 272 cam
- 4-1 extractor

Any input?

Saw this from NS performance ..quit similar with my mod.
Also, notice that also have torque dip at around 4300 rpm..seem like is the nature of the cam.
