Hey whats up yall, its been awhile since I posted on here but anyways....i just recentlly installed new headers, hi-flow cat and a 22" mid-long steel resonator and somehow I have seemed to have lost power especially before vtec kick's in. Is it possibly because the new parts are tuned for mid/high range, or could it be something else? I have some new type-s camshafts being installed soon so it could be possible I just have too much exhaust flow and not enough air comming in. Right now my complete set up is....Cold air intake, headers, hi-flow cat, hi-flow resonator, and (2 1/4") cat-back exhaust....let me know what yall think. Thanks ahead of time.

i think im in the same boat, last year i installed a kteller equal length header and i think its getting too much air flow, maybe needs more fuel.But im having it tuned really soon with Hondata s200/P72

 

o sweet man, keep us posted on the turn out. im very interested in getting some tuning done after I install my camshafts, and cam-gears

 

is the secondary o2 sensors tripping a code? if so it will expletive up ur air/fuel ratios. I had this problem after putting on an exhaust and bought an o2 simulator on ebay for the rear sensor which helped a lot.

 

it could be you need more fuel, i had the same issue on my 4th gen but when i put the afc and got it tuned got alot of power

 

sweet, well im getting my camshafts installed sometime this weekend so hopefully that will level out my problem. Also I think I will check out that O2 simulator and see how that works for me, thanks 2 everyone w/ their info/help

 

Well I got my type-s camshafts installed and it cleared up some power in the mid/vtec range but still a loss of torque overall. anyways I bought a O2 simulator so i'll keep yall posted
