Factory OBD1.
Procharged.
Still getting a proper custom tune.

This Foxbody Mustang came in boosted with a Procharger and still running the factory OBD1 PCM — and yes… we still tune these.

A lot of shops won’t touch older platforms.
Especially boosted OBD1 setups.
But these cars are still very much alive — and when tuned correctly, they run incredibly well.

With a Procharger on an OBD1 Foxbody:
Fueling must be dialed in carefully
Timing needs adjusted for boost
Drivability needs refined
Power delivery needs smoothed out

This isn’t a canned tune situation. It takes real calibration experience.

At Lsxkilr Custom Calibrations, we dialed this combo in the right way so it drives clean and pulls hard.

Boost fueling corrected
Timing optimized
Throttle response sharpened
Smooth power delivery

Old platform…
modern performance.

Yes — we still tune OBD1 Foxbodies.

Long tubes.
Bolt-ons.
4WD Coyote.

This 2023 F-150 5.0 came in with long tube headers and supporting bolt-ons, then went straight onto the dyno for a custom calibration. Once airflow is increased on these trucks, the factory tune no longer matches the combo — especially on a 4WD setup.

Airflow increases
Torque curve changes
Shift strategy needs adjusted
Drivability needs refined

Without proper tuning, bolt-ons and headers don’t reach their full potential.

At Lsxkilr Custom Calibrations, we dialed in this 4WD Coyote under real load so everything works together the way it should.

Fueling corrected for header airflow
Throttle response sharpened
Shift strategy refined
Smooth power delivery across the RPM range

No canned tunes.
No guessing.
Just a 5.0 F-150 that pulls harder everywhere.

Long tube headers installed…
now the 6.2 can finally breathe.

This 2017 Silverado 6.2 came in after long tube headers were added and needed a proper custom dyno calibration to match the new airflow. These 6.2 trucks respond extremely well to headers — but only when the tune is adjusted correctly.

Once long tubes are installed:
Airflow increases
Fueling requirements change
Torque curve shifts
Factory calibration is no longer optimized

That’s when drivability issues and lost potential show up if it isn’t tuned.

At Lsxkilr Custom Calibrations, we dialed this 6.2 in under real dyno load so everything works together the way it should.

Fueling corrected for header airflow
Throttle response sharpened
Shift strategy refined
Smooth power delivery across the RPM range

No canned files.

Just a 6.2 Silverado that pulls harder everywhere.

Bolt-ons added…
now it’s time to make them actually work.

This F-150 came in with performance upgrades and needed a custom dyno tune to tie everything together. Once airflow changes and larger tires are added, the factory calibration just doesn’t match anymore.

Throttle response feels lazy
Shift points don’t match the power
Power delivery isn’t smooth
Mods don’t feel fully utilized

That’s where proper dyno tuning makes the difference.

At Lsxkilr Custom Calibrations, we dial in trucks like this under real load so everything works together the way it should.

Throttle response sharpened
Shift strategy corrected
Fueling matched to the combo
Smooth power delivery

No canned tunes.
No guessing.
Just an F-150 that finally drives the way it should.

Big block power…
modern EFI control.

This 454-powered Caprice came in running Holley EFI and ready for a proper custom dyno tune. Big block setups like this benefit hugely from EFI — but only when the calibration is dialed in correctly.

Cold start behavior
Idle stability
Throttle response
Fueling under load

All of that depends on the tune.

Without proper calibration, even a strong 454 can feel rough and inconsistent. With Holley EFI tuned correctly, these big blocks drive smoother while still making serious torque.

At Lsxkilr Custom Calibrations, we dialed this combo in under real dyno load so it runs clean and pulls hard.

Cold starts cleaned up
Idle stabilized
Fueling matched
Smooth torque delivery

No guessing.
No street-only tuning.
Just a big block Caprice running modern.

Old school 454 torque… with modern drivability.

Classic…
with modern LS power.

This 1985 Cutlass came in LS swapped and ready to be dialed in the right way. Swaps like this completely change how the car behaves, which means the calibration has to be built around the new combo.

Different engine
Different torque curve
Different fueling requirements
Different drivability needs

Without proper tuning, LS swaps often feel unfinished — even when the build itself is clean.

That’s why this Cutlass went straight onto the dyno for a true custom calibration.

Idle cleaned up
Throttle response sharpened
Fueling matched to the combo
Smooth power delivery

No guessing.
No shortcuts.
Just a classic Cutlass that drives like a finished build.

LS swaps never go out of style — especially in a G-body.

Cam installed.
Bolt-ons added.
Now it’s time to make it all work together.

This Camaro came in with a camshaft and supporting bolt-ons, which completely changes how the engine behaves. Once a cam is installed, the factory calibration is no longer even close.

Idle characteristics change
Airflow increases
Fueling requirements change
Powerband shifts dramatically

Without proper tuning, cammed cars usually end up with poor drivability and inconsistent power.

That’s where custom dyno tuning makes the difference.

At Lsxkilr Custom Calibrations, we dialed this combo in under real load so it drives clean but still has that aggressive cam personality.

Idle stabilized
Throttle response sharpened
Fueling corrected
Power carried through the RPM range

No canned tune.
No guessing.
Just a cammed Camaro that runs as good as it sounds.

Procharged and ready to be dialed in.

This 2016 Camaro SS came in boosted and needed a proper custom dyno calibration to make everything work together. Once a Procharger is installed, the factory calibration is no longer even close.

Boost changes everything:
Airflow increases dramatically
Fuel demand rises fast
Torque curve changes completely
Drivability needs refined

Without the right tune, you end up with inconsistent power and a car that never feels fully sorted.

At Lsxkilr Custom Calibrations, we dialed in this Procharged Camaro under real dyno load so it drives smooth and pulls hard.

Boost fueling calibrated
Throttle response sharpened
Power delivery smoothed out
Drivability cleaned up

No canned files.
No guessing.
Just a Procharged Camaro that delivers.

Boost is fun…
but reliability comes first.

This Mustang GT came in Procharged, and before turning it up, we installed billet oil pump gears — a must-do upgrade on boosted Coyotes. Once the hardware was handled, it went straight onto the dyno for a proper custom calibration.

Because with boost, everything changes:
Fuel demand increases
Load on the engine increases
Timing strategy changes
Power comes in much harder

Skipping the supporting mods is how engines fail. Doing it right means strengthening it first, then dialing it in.

This build received:
Billet oil pump gear upgrade
Procharger setup dialed in
Custom dyno tuning
Fueling and boost calibrated

Now it’s not just fast — it’s built to handle it.

No canned tune.
No shortcuts.
Just a boosted Mustang done the right way.
