Some dyno results for the naysayers.

Exactly! Almost all of the stock turbo Rangers with tunes have a ridiculous torque spike, it’s there because it’s hard to flatten. Hitting the stock turbo hard down low causes it to run out of steam earlier than actually tuning it to work throughout the rpm range. These engines make power past 6k if they have enough air. The larger turbo tends to be slower to get spooled and when properly tuned that reduces the stress on the engine down low and allows us to spread that power out along the whole range better.

It's really not hard to fix... Just don't ramp the turbo up so high to get those peak numbers. This is one of my cars, which is a Saturn Sky Redline that I tuned on E50. A lot of the tunes/dynos I see, people ramp up boost to like 26 PSI, but it falls. This gives high peak numbers, but it's not really faster and when you do get into that range, it's harder on the engine for little gain. I just settled on 21 ish PSI flat and worked timing to help smooth it all out.

Getting boost flat on a smaller turbo like this takes a little more effort in scaling things... Ramping it up is easy!

I’m assuming you tune these trucks often enough to know that.

I tune a lot of engines daily.

Right. Like I said… then you know that different systems and combinations work/respond differently. It’s really not important that you tuned a Saturn, we’re discussing a 19-23 Ranger. It’s not even the same as tuning an ecoboost Mustang for that matter.

I tune Fords as well. We also have a Ranger and Maverick, which I used for tuning development. I know A LOT of different tuning platforms.

An Ecoboost Mustang isn't too dissimilar.

The original dyno I posted earlier in this thread was comparing and STi tuned on Cobb and a turbo S2000 tuned on AEM (now Haltech). The means of tuning are just a way of getting things running how you want/the engine wants. For the most part... it's all the same (when you've tuned for like 20 years). Hell, the means of achieving boost on the Saturn isn't too dissimilar to the Ranger... It's not a WGDC table.

What tuner is preferred and I'm just wanting to do few small things tuner exhaust.. but maybe intercooler and more.... thanks in advance

Time has passed and projects move forward. It doesn't seem that much internal to the engine block should need changing although the closest things may be a fuel pump/injector upgrade along with spark plugs - external 'bolt ons' would 'simply' be intake/turbo/exhaust... and the tune to bring it all together.

I guess it cones down to what the driver wants - light to light excitement or something all around?

I haven't gone nuts with my daily driving, multi use truck, just a modest 3 inch exhaust and some intake parts with a tune. I do believe there has been a change in how the truck accelerates - smoother and quicker but I'm curious what the potential hp/torque from the 2.3 ecoboost could be? Without going BOOM of course.
