thanks guys for all the interest/help!

but I am going to try to go back this weekend, so I'll keep you guys posted!!!

I went to Toronto Motorsport Speedway 1/4 track in Cayuga,Ontario. So I think were above sea level more so that could also be affect.

I'll try to rev up around 3000RPM and release it, see what happens hopefully I won't get wheel hop or anything cause that will most likely kill my rear.

what should I shift at? I tried 5600RPM and seems like I loss power

my temp gauge when I finished crossing the 1/4 line, was 1/8 the way...

Well your 60's are horrible. You can have a good rule of them every .1 off your 60 is .2 at the big end. So there is .8 of a second right there. Otherwise your 91 mph trap speed looks about right for a 15 second pass. I'd look into the tune and how messed up that is. Also see how much timing is pulled because i'm sure your way down on power from where you should be. Do you have a check engine light on? I'm guessing your getting a knock retard but that is just throwing out ideas.

That might be the most garbage 1/8 mile time and mph that ive seen in a while. Put it on a scanner and see whats up. Otherwise start modding and have fun.

Heat is absolutely destroying you. Get a manual fan switch to keep the heat down, I would also put a bag of ice on the intake before a run.

If you have a 160 degree thermostat, it shouldent be getting to 3/4 the way (if your talking on the stock gauge).... Get it scanned, Im sure theres some codes waiting for you. And yes, your car should be an OBD1 with the OBD2 port.

A manual fan switch will help you alot especially at the track as described above, think about getting one.

Are the fans coming on? I run a 160* stat, sitting in the stageing lanes mine will sit at the 1st. line on the gauge, fans are on, make sure they are working. I'm sure you need to program the fans for the PCM for the 160* stat, so they come on around 175*, otherwize they won't come on untill 205-210*, kind of defeats the purpose of running the 160* stat, but if the fans are programmed in, then dis-regared what i said.

I was at the track lastnight. My car is almost stock K&N filter and cat-back and ran 2.3xx 60ft spinning and still pulled 14.1 @101.xx mph. Your power is way down!

Go to autozone if you have one nearby and have them pull the codes to see why the CES light is coming on. A LT4 KM will help if your getting false knock. Check all your wires for burns or arching. Check for any intake leaks. Does the car feel like its running right?
DO NOT JUST LEAVE THE CAR RUNNING WHILE WAITING IN THE LANES. Only turn it on to move it up and just push it up if possible and ice the intake between runs.
With a 160 stat and the car programmed to work with it should only be between the first and second lines when fully warmed up(closer to the first line unless your just sitting there).
My best pass was a 2.2XX 60ft 14.025Et @ 100.xx mph Car hooked to good and fell on its face. Then I ran out of time.
I think a tech 2 will work on obd1 or 2 cars but not sure about an adapter. All my f-bodies have been 96 or newer.

it felt like it was running right but sometimes it doesn't feel like it. It's like it cutts out around 5600 RPM sometimes?!?! so I'm going to pick up the LT4 KM and install it and see what happens from there...
