Hey guys so ive left my car sitting for awhile and decided to take it for a spin ,now the problem is its not boosting 18psi anymore it will only boost a high of 14psi cheecked for leaks their was a little leak with the afm in cooler piping which i sorted but still didnt fix the problem was wondering could it be the external wastegate not working properly or would i need new or aftermarket coilpacks? The mods are gt35r 6boost mani 44mm gate etc..
