I don't think replacing your H/E should be any sort of the first like 8 steps to fix the problem...

replacing the H/E while still having the problem is like an ugly woman wearing too much make up...sure the make up may make her looks good, but underneath she is still ugly.

Stock H/E is fine for a stock SRT6 and the improvement you will see is minimal....on an otherwise stock car.

definately once modifications start going in you should replace it in some form.

but for now, burp the system, make sure the polarity is correct, replace the fuse (fuse #15 i think), and then move forward from there.
