no I doubt it, I have new built motor new turbo alot has changed since I pulled that time on the gt2540r and stock bottom end. its just right now I am detuned to what my injectors will handle which is 17 psi at most. Nissan sent the wrong injectors dont ever get a nissan. lol plus you are right to Jamie I was spinning bald DR's pretty bad and that always brings the mph up a few. Less boost also means less torque as well for an SR. My torque wasnt near what it was when I ran my best I missed it badly. So until I get it right its only speculation what will the 13 extra psi will do.
