Did you buy the car brand new? If you did and you only put 93 octane in it, you shouldn't need to pull the fuse. I had problems because my motor was detonating. I got her in Chicago where they have 93 octane, but then I shipped her to California (where my duty station is located) and unfortunately Cali only has 91 octane. I installed my roto-fab and and got her on a dyno and was making 505rwhp and only 470rwtrq. At wide open throttle my motor was detonating and I was already at 95% duty cycle. I bought more mods(mods in SIG) and went to Cunningham Motorsports. They inststalled all the parts and got the famous 91 octane street tune by Ryne. She runs better then stock and performs like a beast. I actuallty picked up more mpg on the highway as well
