Absolutely! For the small gains it makes it's really not worth having.
I'll do the hondata mod and probably a cold air feed at some point.

Any more thoughts???
Still got the jerky "fluffy" hesitation down low even with the full service, new coils, OEM air box back on bla bla bla...
Could this be the exhaust messing up the fueling?
Could it be bad O2's?? MPG is good
Car seems to improve when run and very hot but still hesitates when off to on throttle it's so fudging annoying I'm begining to hate EP3's and there stupid k series engines. :-(

Small update
Check you throttle cable tension.
Ours was very slack and this is my theory behind the hesitation.
The car still coughs (probably due to mods) most EP3's do this. What makes it noticeable is the throttle tension. When slack and at light throttle this "cough" causes a slight rock in the engine which is a enough to shut the butterfly in the throttle body which momentarily cuts fuel and makes it hesitate.
Now when the throttle cable is tensioned this cough does not allow the throttle to shut and cause the stutter. Thus making it very hard to now notice. It's a massive improvement 90% I would say and does not bother me at all now. Once fully up to temp car is beautiful and actually feels slightly faster wot so maybe we where never at 100% throttle position with the slack cable.
Not sure why Honda make them set so slack? Apparently it's common... One theory is to prevent wot when running in....
Anyway my advice if you have this problem adjust your throttle cable before spending any money!!!
