i get the same issues with my setup to the cchh chh chhh
i have std rebuilt turbos w steel wheel on ss manifolds, full hard pipe kit and no bov and pfc with afm just shy of 300kw but i recon its the manifolds not being tuned lengths or the hard piping not being the same length from turbos to intercooler. what i was going to do is run a 2 into 1 intercooler and make the pipe lengths the same from the turbos to the intercooler?
what do you guys recon? and im not giving up the the hard piping kit lol
