Motorvation Chips...
My came with No instuctions or listings as to what had been changed, and my uncles only listed to install it piggyback.
Mine is a stage 2 for an 85 and my uncle is same but for a 90 we were only really after the fan setting changes. But both of our cars idle and all around drivabily is better for the most part. And the 90 had a horid idle issues before the chip change and after it was smooth
The only issue I have with mine and its a small one is the TC locks up abit sooner and seems to take longer to disengage nothing major just took some getting used too, almost too the point I just manually downshift myself. if I don't want to wait the extra second or so
not the cheapest way to get fans on sooner but We are both happy with the results
