I have a 2002 automatic 3.8L and i have a cai for it already, and wanted to increase the intake even more, so i purchased a BBK 65mm throttle body and installed it. i did notice more power and better sound and is fine, but now when i press on the
gas (all the way down for example) when its above first gear, it Does Not downshift to get that extra passing power like normal. it just sits in the same gear and increases in speed slowly. why isnt it downshifting?? did i maybe tweak the TPS, throttle position sensor, in the process? or does the combo of the two intake upgrades mess up the cpu?... whyyy? and what can i do to fix it bak to normal
