Well while i was at the track some people including myself noticed the Corvette when going round 3rd gear after 90 mph maybe the car would just bog down. The RPMs would stay same and not feel like moving fast as it should. Is there anything in the tune that might cause this. Dont know if im explaining myself good.

Do you have a slip from your runs? Know how much your picking up on the big end of the track? What were your times up here?

Just saw this thread. If you would like I can take a look at your tune, see if anything is amiss in the upper rpms.

If you are stalled i think that can be a common problem. has to be tuned out by someone. ^^^

It;s funny cause after i did my stall swap i noticed like to OP the car felt like it fell on it's face slightly.. hmm good to know, and should be interesting after my new cam and tune.

Yea I have a stall in there. I currently have the tune in EfiLive format. What are some things to check in the tune?

Just make sure you have proper A/F and Timing in these areas. N.A. Your goal being conservative should be around .890 to .915 volts reading the o2's, stock engine timing close to 28 to 30deg, zero knock.

AF is at 12.5.- 12.6. Not sure about timing.
