i have a 2011 GSR. currently have an AKUMA Intake, a cat back and test pipe. i ordered an ETS 3.5'' IC w/piping and an ETS external dump down pipe along with a grimmspeed 3 port. i am getting tuned as soon as i finish installing. with those mods, will a new BOV (recirc of course) benefit me in any way? will the stock BOV leak with those mods? or should i stick with the stock one?

 

Stick with the stock one unless you have one of the BOVs that leak at 18psi. I got lucky and mine holds 24psi.

 

guess ill have to wait till my tune then. if i go with a synapse after my tune would i need a retune?

 

Yes, a new BOV to replace a leaky stock BOV requires a retune.

 

thats all i needed to know. just ordered a TiAL QR and had em weld the flange to my LICP. i figured even if the stocker doesnt leak, the tial should still hold boost better than the stocker. thanx for the input
