Some dyno results for the naysayers.

[Frenchy]

No other changes i.e. charge pipes then without dyno tuning it's not a lot of change over stock.

Always the tune helps, IIRC even Mishimoto doesn't make power claims without them.

Not sure where you got charge pipes especially when he said Inlet Pipe meaning before the Turbocharger.

As for charge pipes by themselves obviously won't do anything significant. With an intercooler is different and it's really the intercooler doing the work.

It is known that tuning this truck will give ~40 HP and ~60 TQ, even on the stock airbox. It's interesting to see the difference pre-tune, but almost no difference with the Roush box post-tune. Maybe the Roush box leans out the stock AFR to bump stock numbers, but a tune has them leaned out enough already?

The afr gets corrected by the stock (any proper) tune. The ecu will always go to its target afr as long as it is able to. That’s what fuel trims do every day. It’s not leaning anything out. The Roush intake is still very restrictive but definitely was adding potential for power when tuned. I never included a graph to show the stock intake on the truck with the tune so I don’t understand where you’re getting those figures from.

The

Cool thread. +1 for downpipe. I really think the added air from an intake benefits in conjunction with the downpipe and catback.

When we do the next round of testing it will be on my truck instead of the one used for these tests. My truck is as full bolton as it gets while keeping the stock turbo.

i think it’s a huge improvement over stock without tuning. The gain over 5k with just the intake is pretty big if you ask me. The gain everywhere with the intake AND turbo inlet pipe was huge! t truck has stock intercooler and pipes fyi. The power curve would be much shorter if it didn’t have the intake along with the tune.
I’ll make sure to include a totally stock intake system vs everything else comparison when I do my testing next on my own truck. My truck made over 270rwhp with only boltons, 33’s and zero tuning so I’m going to say that the right parts make quite a difference both with and without tuning present.

 

[Loweredon33s]

So basically saying the best bang for the buck power will truly be a tune vs anything else. Got it.

Depends on the goal. If you want a big peak number with nothing much in between then tune only will yie the largest noticeable improvement, if you want long broad and dynamic power throughout the entire rpm range then it’s going to take a combination of parts and tuning.

Yes, A normal person doing normal things will most likely be happy with just a tune. I’m not normal nor am I doing normal things. I want it to be as good as it can be in all ranges and pedal positions.

This is a 2019 XLT sport, with wheels and tires, 93 octane, stock tune and Roush exhaust.

So glad you opted for the wheels and tires. Try a run without them.

My apologies, let me specify, the truck has aftermarket wheels and off road tires, they are considerably heavier than stock and therefore need to be mentioned since they play a role in power translation to the wheels.
You know, like when someone says they have cams, or exhaust, or whatever... they mean non stock.

Ah! Now I get it. Sorry I didn't catch what you meant. Yes, that makes a big difference.

What exactly are the naysayers saying? Because those #s do not look that good. I realize #s from different dynos are not directly comparable, but don’t all the major canned tunes result in more power? Shit, I’d expect just running 93 to yield more.

That’s a substantial improvement in overall power for just an intake install if you ask me. It’s more than they advertise.

Ah I’m with you. Intake is a nice bump indeed, but tune on top is not as substantial as FP or other canned tunes so threw me off.

I take my truck off road so am wary to install any high flow filter that would potentially reduce particulate filtering.

I’ve got no dog in this fight re tunes either, as even if warranted for the factory drivetrain duration, I can’t imagine it improves longevity. I’d rather have an engine last to a couple hundred thousand, or give it a good chance. Maybe the tunes are 100% safe and don’t increase wear and tear, but I’d rather protect the drivetrain.

I think you need to look at the torque to see the improvement better, it gained quite a bit of horsepower with tuning but the torque is much higher.

So the only gain from the bolt on parts are in the top end. Not often you go there at all. It's low end that you want and even then it's tough to get with a Turbocharged engine.
