Yea I plan on keeping it till it dies [I hope that doesn't happen for a long time]. What do you mean by CARB; I am relativly new to moding an engine. I had a 1989 Legend and I couldn't find any thing that fit that car. It has 200,000 miles on it, I hope to get that out of my TL. Oh how much of a diff does that Icebox make and how many hp do you think your pushing now with all those mods you did?
