MY01 ap1 has k an fipk intake, invidia 70mm test pipe, t1r70mm v3 single and aem wideband installed. ive posted a couple things before on here about how lean it was. i do not have a tune at all currentley but im going to get a giles emu tune here in the next week or so. now with these few bolt ons im running 13.3 pre vtec in 3rd, and a 15.5-16.0 vtec spike, then back to a 14.-14.2 from 62000 on up to 8500. i let off casue i know up top still runs rich some...is there anything that could be wrong?? or is it just caseu of these bolt ons im that lean? would a dirty fuel filter cause leaner conditions...i bought my s2k at 51k and i almost have 60k on it. i havent touched the fuel filter but i was wondering if this was chcanged would it help my situation or just get a tune asap. i dont ever run wot knowing its like this. my idle and partial throttle are perfect still...partial thorttle is 13.ish never over 13.4

 

This is normal
