Any module or tuner that increases rail pressure (pretty much all of them) will have an increased accel delay as the rail bleeds off excess pressure. The more pressure, the more it is noticeable.So I got the module yesterday. I drove around stock with forscan hooked and have an idea of rail pressure. It changes so often and fast. I will look at boost and load while the vehicle is stock. I did put the module on for a little bit yesterday. I can tell a difference especially from a stop. I was driving around town so hard to really test and did not have much time. I will play with it more in a few days. One thing i did notice intermittently was letting off the accelerator there was a delay to when the rpms dropped about a second. It was like my foot was still on the accelerator. I have noticed this before the module but much more noticable with the module. Again i didnt have much time but so far I am thinking about sending it back. I don't like the pedal decelleration thing.

That makes sense. So I watched fuel rail volts stock and then with the module. I don't really notice a difference. Not sure if forscan show the volts before or after the module. I tried watching the actual pressure but it changes so fast hard to tell. Maybe the volts rise a little faster with module, hard to say. To be honest I don't really feel a difference. As I said somewhere else throttle might be snappier, worth the price with the switch? Right now I say no. Truck has plenty of power stock. I will keep it on for a little longer as I am curious if the regens are more frequent. For those of you on the fence my opinion is don't buy it, not too much different. Just my opinion.Any module or tuner that increases rail pressure (pretty much all of them) will have an increased accel delay as the rail bleeds off excess pressure. The more pressure, the more it is noticeable.
I took mine off a few months later. Had a check engine light come on and it was for high fuel pressure. Can’t say the module caused it but it has not happened since I took it off. The CEL only came on once in a few months I ran the module. There was a difference in response.i know this is an older thread. Would the guys that installed these in 18 comment on how they are liking or not liking the Stealth module?
I have one on my 05 6.0. I like it. Causes a hard start in the mornings, but has been getting Lea and less as time goes by. Is it worth the $600.....no. I'd pay $300-$400 for it. Still happy with it though. It takes a couple weeks to adjust to how you drive. Longer ID you're like me and tend to put your foot in it. Good response, less turbo lag ( but it's still there, but less though). I replaced the ICP sensor for the hell of it and the ICP plug. I like it.All,
I just pulled the trigger on one of these. Stealth Modules Wanting to do a Delete.(for some time now) and having done them on my past rides. I called and spoke with Eric. (super dude!) he explained to me how why etc... so I decided to pull the bank trigger.
Ill do my best to report back. pics and all.
My 05 is the same way. Anything above 80mph she doesn't like. Which is fine with me cause I love cruising at 75mph and feeling her growl.Stealth
My truck hates anything over about 72 MPH. Mileage falls on its face. Hard to do when speed limits are 70, 75 and 80 MPH out here. That and the fact that I like to get to my destination.
