olddog Posted April 2, 2012 Report Share Posted April 2, 2012 We just tried to tune three Cadillacs, one was a CTS-V which was easily tuned for both engine and transmission and two CTS 4's neither of which we could tune. It would seem that, to date, HP Tuners does not support the software for tuning the direct injection units. I know their first priority is Corvette, then pony cars and anything using the same basic power platform (LS series engines). Blown Caddy's are next in priority but the direct injection cars get little attention which, I think, is a mistake. This said, does anyone know if there is a real tuning system available for the CTS with direct injection? I am not talking Diablo etc. rather a real system such as LS Edit?
