Got a 13 fx4 5.0 have a 5 star tune (87 perf/tow) the shifting is way better than stock but still seems conservative on the power side. Does anyone have experience with SSI tuning on a 5.0l? They claim they are substantially better than 5 star.
I have 5* and MPT, MPT being the most powerful. Have only heard horror stories about SSI grenading engines.
I think the consensus with the EBs is SSI has more power, but could blow your engine. 5 Star is a little more conservative, but safer. I'm sure I'll get flamed here, but there are several threads on this, and this was my take on it after reading them. Not sure about the Coyote tunes. I think there is one guy on here that loves SSI, but I would never put one on my truck if I intended to keep it for 5+years. For that matter, any tune.

5star, MPT or Omega for 5.0.
Do your research on each and decide.
SSI pops motors on EBs so I wouldn't trust him tuning my lawnmower.
Alrighty thanks for the feedback.
I've run 5* in my 14 EB, 87 and 91 tunes and it was night and day difference, just the right amount of power for me but not at risk of destroying the engine. I have 87 and 91 tunes for my 16, but other than pedal response it didn't make much difference, and since this motor has a tick on acceleration and the trans shifts feel wrong, I decided not to run it, wasted $160 on them.
Shawn Ellis is a worthless liar and thief. I ordered and paid $515.00 + $15.00 shipping for an SCT X4 programmer with 3 custom tunes on Monday 5/14/18. I received the X4 on Friday 5/19/18. I filled out the custom tune form on Monday 5/21/18 and sometime later that day I received an e mail stating he received the order and I should receive an e mail or phone call within 48 hours.
Since I had not received anything by late afternoon on Thursday 5/24/18, I called Shawn and he said he was in the middle of working on a tune but since mine was an easy 5.4 tune, he would send it out that night or the next morning. Nothing happened on Friday as he stated so I sent another email yesterday, 5/26/18.
Still nothing in my in box this morning, Sunday 5/27/18, so I have come to the realization that he doesn't plan to send me anything in the future except maybe more BS and lies if he would even answer the phone. I plan to file fraud charges with his local PD on Tuesday 5/29/18 as I don't have any other recourse left.
I guess I should be glad the worthless SOB at least sent me a NIB X4 even though it doesn't do me any good with out the tunes installed.
With all the crap out there on the internet and horror stories, I can't believe people are still sending their money to him.
Just a quick Google search should be enough to turn you away.
