RennTech Mod for 2011 E350
Hey guys, anyone do the ECU Mod by RennTech on their E350? I'm looking at doing it and wondering if it will really perform any better. +22HP is mighty tempting....

More peak power, better throttle response- it's a nice mod. When I was working there we did a bunch of them, and everyone was usually pretty happy with it.

Thanks Speedriven1 I'm on the fence because it's $1450. I'm just wondering if it'll be worth the cost. LOL
