I had been running with both fuses removed until apkano pointed out that my brake lights didn't work
I immediately reinstalled the fuse that also controls the brake light and haven't noticed too much difference whether 1 or 2 fuses are pulled.....I can still do brake-torque starts, and get it totally sideway in corners
with just 1 fuse removed. The only draw back I noticed is that my wing is always up. But this may be due to something else. I also run with no TPS. As a result I have a fully lit Christmas tree on my dash.....J/K only 3 lights on all the time.
BTW my car is a 2005 Limited.....I know the 2004s are set up differently
