Got rid of the greddy td05 turbo as it was a little laggy for track use so finally made my mind up and decided on this......... Tuning developments td04 hybrid billet with 1.8 bar cartridge had a full 3inch system built by gr performance.... great quality!! **had car on dyno made 295 at 1.4 bar and that was turbo alone without boost controller set up or before 3 inch system was made! will be back on dyno soon at 1.8 bar see what that pulls great turbos would recommend to anyone - thanks to tuning developments for supply the turbo!!
