Hey,
I was just wondering if anyone has installed one of these on their 6gc. If so, was their a noticable difference in performance?

from what i've read theyre total crap. basically it just tells the PCM to dump more fuel and ****s with timing. why trust a chinese box to do better than your Toyota PCM + a human touch of tuning? pickup a used safc type device for cheap to do the AF tuning and then use that to monitor knock while you manually adjust timing.

I bought one cheap secondhand and installed it about a month ago. It really just changes the fuel, shift points and timing like Bitter said. Plus it made my check engine light come on. I'll probably uninstall and sell it on eBay soon.

all things you can do better yourself. if you have an AT play with the slack on the cable from the throttle body to transmission. i took about 1/8th inch of slack away and it'll hold the gear a little longer at lighter throttle, just perfect for my tastes!
