Long story short version...Max speed was 135mph but it fell off before the end of the straightaway. That was the 1 good lap. One good lap out of about 25 before I parked the (deleted) thing and vowed to get the answer(s) from a group that has experience (that's this forum).
For the balance of the weekend it would fall off (just miserable low power) and it was good for a whopping 110mph.
Likely there is something in the engine management system that is causing it to fall off in power.
Likely you guys have answered this before,but please help this newby.

PS, to noavail, the ABS and ESC fuses were pulled out in one of the run sessions.
inter cooler pump failure....it gets hot, sensor says, shut down super charger, thus no power....have the ic pump replaced, also double check IC sensor, they can go bad as well...use the search feature on here, to read many many cases of this happening....there are a couple of better pumps you can replace the stock pump with...Johnson would be the preferred by many on here
