I have a 2008 Shelby GT 500 with a 2.8L Kenne Bell and I have the Stage 3 Kit and when I get on the car real hard it went into Failsafe Mode does anyone know how to get it fixed. It has recently been tuned and it made 812rwhp and 797rwtq and it just started going into Failsafe Mode please if anyone knows anything please let me know Thanks!

Sounds right to me....have read this a couple of times on others that have had the same problems!
