Anyone tried a Fuse Pull on LS3

[95RedCamaroz28]

so the L99 engins had a problem with performance, but after the fuse pull there was an increase in performance. I was wondering if this would increase performance on LS3 engines. Has anyone tried pulling the fuses on there LS3.

I did and left them out overnight, didn't seem to make a difference but I've had 93 octane in it since the day it arrived. There's another thread where a couple people said it helped though.

+1 It didnt do anything for me. It pretty much only helps if there was low octane put in your tank at some point.

I did...


puled them and left them out overnight..


Didnt feel any different in normal city driving..


I had my son in the car and I got on it..

He said WOW! This thing feels better...

The rough idle is just the lope from the cam thats in it...

But going through the gears is a whole lot smoother after the pull..

And the revs when you go through the gears are alot smoother too...


It feels better than it did..


If I was you even if you do know your dealer put 93 in it.. still try it.. it wont hurt anything...


And I dont know if some of you have noticed but when you put it in first and start to go up a hill(my driveway is a hill) it kinda bogs down..??

Doesn't do it anymore since I have pulled the fuses...
it feels smotther..
