i am fairly new to newer emission gunked motors of the 90s and today, but i was wondering if i could remove the egt and air flap just and put block off plates in? would this hurt performance at all ? or will the computer get all screwy? i have a 92 2.5 turbo 300d . i realize i would have to plug the vacumn lines going to these 2 devices. any help would be greatly appreciated! thanks again
