Mods are in my signiture. Yes stock turbos, the 22psi is a little high, Shawn from SoCal is going to adjust the tune to get max boost around 17-18psi. A lot safer, until I get upgraded turbos.
So were the boost levels the same between LMS and SoCal?
No, LMS was around 17 max boost.
So it makes sense that you made more power..I'd like to see the comparison at the same boost level
I just wanted to come in here to see the results of our tune versus others on the market. And I was very pleased to see how much power we made versus a tune with so much more boost being in the tune compared to our tunes.
I was concerned with the boost levels until I saw you are getting them lowered. Initially my post was going to be for a link to our new EcoBoost piston/Rod upgrade for when you needed it. but just in case, here is the link
http://www.livernoismotorsports.com/products/EcoBoost-Piston-and-Rod-Combo.htmlMaking power with high boost is easy, but dangerous. This is why we target a specific boost range for our tunes and spent a great deal of time fully understanding how to not only limit, but control boost on the ecoboost vehicles. We see tunes all the time that have a ton of boost in them to make power, but it's not the correct way to do it and is flat out dangerous. We can make a tune that makes 20+ lbs of boost, that part is easy, but we know what the engines can truly handle over time and what they cannot.
The only way we would ever do a tune that aggressive would be for race fuel, and even then only with written consent from the customer knowing full well that their truck was going to fail because of the stress and high probability of detonation. Being you are on 91 octane and the engine is 10:1 compression, that makes it even more of a concern to us. We wouldn't even consider doing that on 93 octane, this would be race gas only for us, which we do offer.
This is where proper testing and development becomes critical as either A. the tune is designed to be that aggressive all of the time, which is very dangerous, or B. The tune has not been setup for all potential possibilities that could create a high boost situation. There is a reason we have done over 900 dyno runs on EcoBoost f150s, to recreate almost every situation possible.
5 extra lbs of boost for only 8-10 more hp seems rather counter productive. The turbo is well past it's efficiency range, so it makes a great deal more heat, to only (hopefully) have the timing backed off and make near identical power, even if it were in the efficiency range, 22# on pump fuel for anything is just flat out dangerous (again, being 10:1 compression with that much boost just makes matters worse). In addition, if these were runs 1 and 2, I am assuming our runs were done afterwards? If that is the case, it's even more impressive that we make the power we do at 5# less boost, and already being heat soaked. I am completely satisfied with that validation of our tune, its effectiveness, and how much safer it is than some other tunes on the market.
