i have an 89 civic hb with the DPI piece of *** D15B1. my question is, if i remove the plate for the secondary injector, will i still have good performance? because it looks to me like the secondary injector plate ***** with the airflow real bad.if i could rig it so that the 2ndary injector diaphram opens when the main throttle plate opens, i think it should be ok. has anyone done anything like this before? thanks for the help.

 

I dunno that sounds like a lot of work.
