I just got a Stage II and 170 Thermastat. From sales@tbichips.com is the email. I spoke with Brian. This cost me a hundred bucks. I have a 1985 everything is stock except for engine is 1988 instead of 1985. Brian helped me find my computer under passanger dash and told me what the box looked like. 6 x 8 Silver box. That was worth the hundred bucks.

This chip made a huge difference threw all RPM's. I tried the chip with out the Thermastat swap and got some slight pings at high RPMs because of high temp and cheap gas. My average temp was about 225.
Then I flushed radiator and installed the 170 thermastat. Drove to the gas station and filled up with some 93 OC and added some OC boost 6 points. Now fans kick on at about 178 something. My temp avg. is 181. It stayed that way on a 400 mile trip today 50 to 1++ plus miles per hr. speed.

Anyways this chip rocks. My Vette feels much more powerfull. Burns much rubber. I drove it today about 400mile trip on I-75 my avg. gas millage was up 3.6miles per gallon and I had my fuz buster, and plenty of cars that wanted to run very high speeds with me on the Interstate. I cant tell you what the new Top end on the car is but it seems way way faster top end than it was before.
I know there is a guy with a 1998-2000 Red Mustang I think, just north of Ocala that wishes his top end on his mustang was somewhere close to what ever it was.

Thank you TBICHIPS for this mod it made my day.

Hey if anyone knows how in the world to get a steering wheel off so I can put my new one on send me something.
