Ok well it's bound to happen to make this thread...
But seriously, pulling the 15amp Room fuse on the driver's fuse panel really make a difference?
I know taking the ABS/DSC fuse (The 60amp or #7 fuse) will help with dynoing and give me the real power the car has... But I don't understand how a small little 15amp fuse will actually change and make an increase? Can someone please explain this?

 

i have a semi-automatic and before i took mine out it would redline and ping out 7500 rpm and i could only down **** at 4000 rpm. after removing it it now redlines at 8000 and i can down shift at 4500 rpm. so its made a pretty noticable change in power

I believe there is another thread about this....

 

/\Can you please give me a link to this?

Edit: NVM.

 

I never heard of this before.. if you took your fuses out, doesnt that just reset your fuel trims for a short period of time, then the PCM relearns them? I take it this is for a short burst of power when running a dyno, and not a permanent change?

 

I can't find it, will you post it here? I'd like to read up on it.

 

This is the best explaination http://www.racingbeat.com/PCM.htm

 

I finally tried this yesterday.
First, I had my eccentric shaft sensor re-set at the dealer due to hesitation and bogging down when at WOT. They checked compression and the cat first before doing this.
I have the BHR ignition set installed (around 4 months now).
The e-shaft sensor re-set seems to have solved any hesitation & bogging problems problems.
My impression after pulling the room fuse is "maybe?.....maybe not?".....it's hard to tell for me if there is more power.
I'm going by the Butt dyno..........although perhaps slightly more pull at high rpm's is all I can really guess at.
I would need to test at the track or a dyno to know for sure.
The car would not start the first time after pulling the fuse and idled kinda rough, cel stayed on the whole time the fuse was out.
