I know this has been talked about in the past just wanted to see if anyone is still running the line booster's and what do you think about them.

Been running mine for about a year or so now, I don't intend to take it off until I have an alternative method of controlling the line pressure. Still works great.

Just got mine today and put it on. So far I love it.. Really helps the sloppy shifting when you get into the truck a little.. Best money spent on performance parts yet..

I've had one for a while too. Got it when there wasnt a tuner for us out yet. Definately noticeable improvement! Trying to offload mine too if you decide to get one.

I still have and run mine. No issues and does great! Very easy mod!

This is one of those questions if you ask 50 people, 25 are going to love it and 25 are going to say it is useless. On the older 545rfe I think it worked better because the trans didn't have the same learning logic as the newer ones do.

I will say I have an 09 with the newer 545rfe and have the sonnax on and I think it made a difference. Sure the first few days were nice, but then the learning logic of the trans kicked in and adjusted the pressure back down. Even after all of this, my 2-3 shift is hands down better than it used to be. Before the Sonnax, it would have a long pause (like it was thinking where to go next) before it would shift. Now I have none of that and it shifts just like it should.
