double triple check that you dont have a crack in your up pipe. My spool up was getting longer and I had a cracked pipe now its spools really quick with my Powermax.
I just replaced my Y pipe last weekend due to a a crack in the flex pipe actually it was separated by 1/4"...
I was able to do it all in 3 1/2 hrs. But I think it would be a big pain to try and take it out without removing the turbo. I can take off the turbo in a hr.
It should barley be in the front of the bottle, around 1/3" while cold. You might be a little overfilled and it bled off a little of the pressure is what you smelled.
