    Just thought I would drop you a line and say how happy I am with the performance of your 7th injector upgrade kit for the TRD unit. I just wish I hadn’t wasted my money on the TRD unit the first time! All the problems (knocking, surging idle with the A/C on, lack of power, etc.) I had before are now gone! Your instructions were spot-on and easy to follow and the quality of parts was excellent! Thanks again, Scott..
