I've always wanted a Grand National since high school, Feb 20 I bought a 1986 T-Type with t-tops,one of the happiest days of my life. Got her home and started mods 1)fuel pump and hot wire kit,2).009 injectors,3)down pipe3in internal waste gate,4)te 60 turbo and a 3000 stall,93 turbo tweak chip,hot coil pack,K&N air filter,turbo is at 16 psi and the car still runs like its stock need a good tune any info will help I would like a shop I can drop it off at and they can call me when it's done. Any info would help thanks.
At only 16psi the car won't feel any different than stock. You need to add some boost which will 100+ octane or an alky kit.
Yep, might as well run a stock turbo at that boost level and leave the D5 in it. Life in a Buick begins at 20psi.
