As i said in my previous post their reputation is quite interesting and the Facebook group is quite entertaining. Im not looking to defend my purchase OR my choice of tuner. That video you posted up has an explanation behind it one of which I'm not going to go into as its stupid and petty in the tuner world. I didnt post in this thread to go into detailed explanation about the tune or tuner. All i care is that it worked 100x better than the boostmax.
As far as dyno time in my Expy, no it has not seen the dyno, nor does it need to see one for the tune. I bought the JMS Boostmax and Pedalmax cause i saw a few dyno runs and video showing a 90hp increase. Turned out to be baseless claims and to top it off downright dangerous when it fails on you in -1 weather.
And you know as well as i do owning a high performance vehicle a canned tune is nothing more than some timing added and rev limiter change to the stock pcm. This is not that. Not even close.
Btw guys there are MANY tuners out there for these trucks. Dont need to rely on just 5 star for a tune.

Ok I’m not trying to argue but I can’t help myself. If your tune wasn’t custom built with your truck on a dyno, it’s a canned tune plain and simple. Unless maybe you were data logging then sent the results to them for them to adjust the tune which it sounds like you didn’t do that.
The tune was built using another customers truck or a shop truck. Not saying it won’t work as that’s how everybody does it. My tunes from 5* are canned. Are they what came in the tuner from SCT no. I had to fill out a form with my other mods, gearing, etc. they then sent me my tunes a couple days later. That’s canned plain and simple. Doesn’t bother me none.
I’m not knocking the tuner you used at all, the results are impressive. But I guarantee you if there is an Expedition running around with 450-600whp with a stock bottom end they are on borrowed time.
With that said I agree 5* isn’t the only player in the game. But while I was doing research them and Livernois had the biggest following and the best most consistent results. Only made sense for me to go with one of them. If I was interested in racing or looking for a record then I’d go with your boys in a second no doubt.
Either way sounds like your truck is a beast. I applaud you for that
Ok. So dont buy a tune from them. Problem solved.
Back on topic, has anyone tried the vent to atmosphere mod at all for the sound?

I think Jski on here did it and said after a couple of days it got annoying. IMO there isn’t anything much more annoying then a loud ass blow off. People already know you got a turbo. Do they really need to KNOW you have a turbo???
