my first calibration for my 09 si is the CT Engineering stage 2 with the 3.15 pulley and 520cc injectors. It automatically makes the low vtec at 3200rpm. Now when i chose my second calibration which is my CAI, race header and catback it makes the lower Vtec at around 4200rpm. Is it okay to leave my second calibration with the lower vtec at 4200rpm or should i make it the same 3200rpm as the first calibration ?
Please help :)
Need help with the lower vtec level on second calibration
Re: Need help with the lower vtec level on second calibratio
If one is for a supercharger and one is not, and you have a supercharger then you should not use the naturally aspirated calibration at all.

alright thanks, i'll get rid of the second calibration.
