'05 C6 Throttle Response

[Marc p]

Hi Guys,

Does anyone know how to get rid of the throttle lag in an '05, I looked at the Vitesse and a couple of other throttle controllers but they do not work with with the '05, I have been looking at handheld tuners (i.e. HP Tuners, Diablosport, iTSX) but can't see any definitive info that I can modify throttle parameters, before I go through and start contacting all the manufacturers I thought I would ask if anyone here has got any of the handheld tuners and if they allowed throttle tuning?

Thanks

Marc
