I just finished making a twin turbo system for my 93 corvette. i got it all together from a universal kit. one turbo for each pipe of exhaust. i can only get 4-5 lbs of boost even with the boost controlled connected wide open. the turbos are to4e and i also wrapped the exhaust pipe.. it also wont build up boost until second gear and it is an automatic. if you have any further ? email or any answers please let me know what you think.
