F53 Performance/drivability upgrade.

I am looking into getting a five star tuning “kit” for the engine. It shows the 3V responding good to the upgrade. I just installed a Hellwig rear sway bar and that made a big improvement. Hoping for the same results with power/drivability to the engine/transmission. Any comments in this area would be appreciated as well. Thanks

Sumo springs, koni shocks, and a steering stablizer. Worth every penny.

If you have the new 6 speed transmission, don't expect much from the tune.

With the 5 speed transmission, it programs the shifting of the gears for smoother downshifts.

As far as more power, if your not needing to floor it, to do what you need to do, you won't see more power. Added power comes in with it floored.

Consider a rear track bar. Depending on how much overhang you’ve got aft of the rear axle, it can help a lot when driving in strong crosswinds.

I'm pretty much with Twinboat. Our old rig was an '04. It had the 4 speed trans. The 5 Star tune made a huge difference with that rig. It redid the trans strategy so it held a gear longer before downshifting. Our '19 has the 6 speed trans. Not a big difference but it will hold a gear a little longer before downshifting. As far as more power, I really don't know for sure as I put the tune on it when it had about 100 miles.

I did the CHF, put on a steering stabilizer and a rear trackbar. I am very happy with the handling and don't see the need to do anything else.

5Star big difference on my 6 speed. More low end torque and better shift points. 4K miles with stock tune. Not disappointed.

One need be aware that Ford takes the view that aftermarket tunes void the drive train warranty and Ford clearly states so in your paperwork. Ford mechanics routinely search for aftermarket tunes when doing work and can detect deleted tunes.

The extra low end torque you feel is due to reprogramming the gas pedal.

The throttle is electronic and the tune makes it open more for the same amount you typically press down the pedal.

If you were to push the pedal more, before the tune, you would get the same torque feeling.

All torque and HP measurements are done on dynometers. All reading are measured at full throttle, as the RPMs climb from idle to the max RPMs.

Here is a post by a tuner who breaks it down.

Thanks twinboat, I’m going to check out the info you shared. I have a question though, when climbing in the mountains my RPMs run between 4000 and 4500 rpm’s. What is the recommended maximum rpm’s for the V10 engine in this situation?

Excellent explanation. I've got a motorcycle with tour and sport modes, and that's all it does -- reprograms the throttle linkage. It's amazing how much more power you get by opening the throttle more quickly

Here's a list of what it actually does:
1.
Fuel Tables



Fuel Control – Fuel tables are modified for either better economy or all out performance. Depending on your needs is how most tables are set up. Most RV’s that go into Open Loop use this fuel table for its fueling requirements. Most V10’s will not step up into Open Loop (power enrichment) at WOT and from the factory are calibrated to operate in Closed Loop which restrains power levels. By correcting this power enrichment function alone can increase power and toque from your V10.

Drive By Wire


Drive By Wire – improvements will be much better throttle response, step on go pedal, vehicle will respond quicker…this DBW system is a torque driven system, it works by taking a certain amount of torque via engine and wheel and applies it to what the driver foot say it needs; a better way to explain it is its a torque limiter. It only allows so much torque at a given pedal position. Stock tables are conservative and numb at best and that’s why one would feel some times a lag or a goofy pedal with DBW systems. For a V10 this is one of the most critical areas that must be addressed and modified to generate more torque and throttle response. By reworking the OEM strategies makes your V10 seems as if 2 more cylinders were added over night!

Timing


Timing- can be increased in most RPM areas for improved Torque and HP. Running a higher Octane fuel will net more power and economy. However, with a V10 2v or 3v even running 87 Octane fuel can yield some respectable gains in power and torque over stock
