If I had a throttle body and tune done on the same day same dyno and baselined at 386 a reasonable expectation would fall in at 400 when all was said and done. Its a fact that a tune nets these cars 15hp on the very high side. GM simply did not leave anywhere near 50hp on the table in tuning even with the throttle body (wich is worth less than 5hp). Then again maybe this tuner of yours is about to open a whole new door to the tuning world wich I would be happy to see happen and im sure im not alone on that. Curious on Tims take on the log file you will send him. Im glad your satisfied with it thats the reason you went in the 1st place.
