So, after freeing up both the intake and exhaust I was greeted with the pleasant surprise of crisp throttle response, more power, better acceleration, and a wonderful sound. I was also greeted with the unpleasant surprise of the stock ecu's 8.5 psi fuel cut

It was fine while the weather was warm but when it started to cool down I would have to shift early to avoid hitting fuel cut, and when it actually got cold it was so bad that I couldn't even merge into traffic. So I babied her around for months saving for an ecu (I did not an still don't trust band aids like fuel cut defenders).

well, apparently secondary injectors don't like going unused for long periods of time so when the weather warmed up and I tried to boost I was getting all kinds of bucking, studdering and hesitation. I changed the fuel pump...no help. So next on the lest was the in-tank fuel pump sock, I cracked it open and discovered a fair amount of rust , varnish and sediment.

First step was to drain the gas. Make shift fuel can FTW!

Then the insides:

I wan't going to pay to have it cleaned, so I researched/tried various DIY methods:
There were some guys (apparently malnurished contortionists children) who reached in an scrubed their tanks...no real man can do this.
There was a redneck on youtube shaking his tank with small rocks and old gas inside....tried it, it does NOT work.
There were some VW guys putting acid in their tanks...as a general rule nothing VW guys do is a good idea, lol
Finally I ran across a product called evapo-rust that made some pretty bold claims and has been used by motorcycle guys with good success.

All I can say is WOW! I picked up a gallon ( I would recommend 2) , poured it in and proceed to rotate the tank into a variety of positions over the next 3 days allow roughly 6-10 hours in each position.
