Is it possible that changing my plugs to a tr6 and list hp and tq?
Changed my stick plugs to tr6 a few months ago so i went to my tuner to retune as he suggested and I’m down on hp and tq from last year ?? I had 487/498 with a very old belt on it changed my belt this year Cus it was slipping abit changed the plugs and now I’m down to 473/468 ?? It shows my boost is dropping at high rpm from 12.1 to 9.2 . Originally my timing was at 18 he tuned it up to 24 and I’m still down quite a bit . Tuner says it could be the plugs ?? Can this be ?? Plz help thanks
