    Boosted GTO dies during wot

    Car has been on an E85 tune and I am retuning for 93 octane. Made a few runs to adjust the boost ve table and it started shutting off at the top of second. Sort of limp mode and then surging until I stopped, turned off the key, remove the key and then it would start and run like normal. Caught it on the scan---looks like the tb is closing by itself. It has a Nick Williams 102 electric tb that is "supposed to be the updated supercharger version. Anybody seen this happen---any thoughts? No Maf, no air filter. Thanks

    Sent a pic of the TB to NW and he said it was the N/A version. Getting it replaced. The dealer sent the wrong one.-GRRRRRRRRR

    Also at what coolant temp does the ecu go into open loop? i see you are at 176 when it does this.

    The flex has a sensor and will not affect anything until a certain percentage, which with 93, it will never get there. It was the wrong TB sent to me. Dealer is sending the correct one. Goes into open loop at a percentage of throttle pedal.
