Hi, i have a 1987 rx-7, and i was wondering if anyone has ever tried putting in a new proformance chip in a rx near that year? I'm especally wondering if someone has used the GTE stage 1 and 2 performance chip and if it worked.
If anyone has tried a performance chip, did it work? Did it add a notticeable HP gain?
