I put the TRD SC on my 96 4Runner SR5 4wd...it took about 4hours.
I also did the TRD tranny cooler and the "free fmu" was then part of the trd install instructions

It pinged a little for the first night and next day/night...then the computer made the adjustments and no pinging from then on.
The truck had 110k miles on it when the SC was put on...I had taken perfect care/maintenance of that 4runner so it was in perfect shape. When I sold it, it had 135k miles and never had one problem. Auto never slipped...never pinged (guess I was lucky)
My 96 4Runner with the SC ran 9.7 sec in the 1/8th mile and 15.6/15.7 in the 1/4mile...not bad
I would definitely recommend the SC...i couldnt imagine driving my 96 without it...it makes SUCH a big difference. One of the reasons I bought my 05 was to experience the trd SC on toyota's V8 and all-wheel-drive..but, like others waiting on TRD, I dont think that will happen now

I love my 05, but would love it even more with another 100hp
And I always use 93octane in all my vehicles before and after the SC
