has anyone purchase this from GTM.was it user friendly or was it simple for a local turner to use it?what horse power gains? with what mods?
here is a brief description of the GTM Motorsport Spec ECU flash

GTM Spec ECU flash will eliminate any unnecessary check engine lights commonly found when upgrading to a standalone, but does not remove the important codes so they still come up if a problem were to occur. it also stabilizes the idle and eliminates idle hunt especially when using upgraded high lift cams ,This is accomplished by having full control over the ECU and making it stay in open loop during idle, We also adjust the rev limiter, speed limiter, Idle RPM set point, and remap the Throttle Control for better response.
