ses Light comes on after 70mph its a bolt on ls1 camaro tuned and a stall and when im driving it after about 65mph the SES light starts blinking at me and once i slow down to slower than 60 or so it stays off, i had someone tell me it might be the wheel speed sensors (i have 3.73 gears and taller tires than stock) but im not sure any input would be appreciated thanks Guys.

First step is to see what the code is. Flashing SES usually means a misfire - but could be anything. Even though it's off history codes will still be stored.

I have seen EGR codes do this on other cars. Try to keep track of the rpm and load rather than mph. It will throw a code when cruising between 2k-3k rpms as this is where the EGR works. Drivability will remain the same. Solution may be as simple as turning off the code.
If its miss firing then you should be able to feel the hesitation. Do you?

I had this happen on my 02 Chevy 2500HD with the 6.0 and it ended up being two fuel injectors that were going bad. Car ran fine but would blink the light at just about the same speed that you stated. Truck was still under warranty when it happened so they took care of it for me, but just thought I would throw that out there.
