🏆 Quality Over Cheap — Every Time
At Lsxkilr Custom Calibrations, we know our labor and pricing might not be the “cheapest” around — and that’s by design.
We don’t cut corners. We don’t use low-quality parts.
Every vehicle that comes through our doors is treated like it’s our own.
We quote and install only top-quality components, because that’s what we run in our personal builds — and that’s what delivers lasting performance and reliability.
So if you want the best for your vehicle, not just the cheapest option…
Look no further — you’ve found the right shop.
🎓 Certified, Trained, and Trusted
At Lsxkilr Custom Calibrations, we have formal training in EFI and Diesel Tuning and are certified by industry-leading organizations in custom tuning.
We take pride in combining real education, verified credentials, and years of hands-on experience to ensure every calibration is precise, reliable, and safe.
⚠️ Don’t Let Just Anyone Tune Your Vehicle!
In every professional industry — whether it’s doctors, electricians, or mechanics — there’s a process of education, testing, and certification to ensure the person working for you is qualified.
Unfortunately, the high-performance tuning world isn’t regulated the same way.
No experience? No problem. Buy a dyno, watch a few videos, and suddenly there’s another “tuner” open for business.
That’s why credentials matter.
Before you hand over your high-performance vehicle to anyone, ask the right questions:
- What training and certifications do they have?
- What experience supports their tuning process?
- What makes them qualified to tune your specific platform?
Your vehicle is a major investment — it deserves to be in the hands of someone who’s proven, trained, and certified to do it right.
Experience. Education. Certification.
That’s the difference between guessing and genuine tuning expertise.
FREQUENTLY ASKED QUESTIONS:
Q. How do I get my car Scheduled in to get Custom Calibrated/Tuned?
Check These Out for Quick Answers!!
Almost all the questions we get asked can be answered below:
A. We are a appointment based business. Best form of contact is via email.
A. 660 US Route 24 unit # 32 (The VERY LAST ONE NORTH) Topeka, Kansas 66608.
(WE ARE ONLY LOCATED IN TOPEKA!!)
-We moved to Topeka, KS in 2024. You will see all sorts of old information online of our old address. We are ONLY in Topeka.
A. We’re a full-service performance and speed shop — equipped to handle everything from basic installs to full custom builds.
We’re authorized vendors for numerous performance product lines and ASE Certified, along with multiple performance-specific certifications.
Our team has the knowledge, experience, and tools to take care of your project the right way.
A. Anytime you change how air moves through your engine, the tune must be updated to match. You’ve invested in performance — make sure your tune unlocks the engine’s full potential.
Mail-order tunes can’t provide the real-time feedback and custom adjustments that your specific vehicle needs.
At Lsxkilr Custom Calibrations, we use our expertise in SCT, Holley EFI, and forced induction systems to deliver precision, power, and drivability — treating every vehicle as if it were our own.
A. Two things: time and experience.
We spend more time perfecting every detail — idle, throttle response, transient fueling, and cold starts — to ensure flawless results.
Each tune includes a complete MAF transfer calibration and thorough data review using freshly calibrated widebands.
We don’t rush or guess — we tune until it’s right. That’s the Lsxkilr difference.
A. The honest answer — as long as it takes to get it right.
Simple setups can be finished in about three hours, while more complex builds may take longer depending on hardware and system adjustments.
We take time to inspect, prepare, and build your custom calibration before the first pull.
For the best results, plan to drop the car off for the day so we can focus without rushing.
A. Every vehicle is unique, and so are our tunes — which means power gains vary.
We don’t sell “cookie-cutter” tunes or quote numbers just to impress. You’ll receive a dyno sheet showing your actual results.
Remember: true performance comes from precision tuning, not one-size-fits-all calibrations.
A. Scroll to the bottom of this page — we’ve included a Full Injector Calculator to help you determine what size injectors your setup requires.
A. We focus on performance and reliability, not fuel mileage testing.
While some customers notice better efficiency after tuning, the dyno measures horsepower and torque, not long-term MPG.
Fuel economy results vary greatly based on driving habits and vehicle setup.
A. We require a $100 non-refundable deposit to secure your tuning appointment.
This helps us keep the schedule open for customers who are serious about their tune.
Your deposit is applied toward your tuning total at the time of your appointment.
A. Unfortunately, no — for safety reasons, customers aren’t allowed in or around the dyno area during testing.
A dyno operates like a treadmill for your car — the vehicle is under heavy load and moving at high speeds.
For your safety, we ask all customers to remain in designated viewing areas while we handle the testing.
A. A Loaded Dyno uses an eddy current brake to apply force to the rollers, simulating real-world driving conditions like road load and aerodynamic drag.
An Inertia Dyno simply measures acceleration against a fixed mass roller — similar to spinning a heavy wheel.
Loaded dynos allow for more accurate, repeatable tuning under real driving conditions.
A. If you ran on our Loaded Dyno, it will typically read 10–15% lower than an Inertia Dyno — because it’s applying real resistance to simulate the road.
Our Mobile Dyno (inertia-only) has 3,600 lbs of force built in — close to vehicle weight — and offers consistent readings.
“Hero numbers” from other dynos often come from lighter rollers or uncorrected data. We focus on accuracy, not inflated results.
A. Properly functioning front O2 sensors are critical for accurate fueling and drivability.
If they’re not working correctly, we can’t complete your tune properly.
Faulty sensors are one of the most common causes of tuning delays — so please inspect or replace them before your appointment.
A. If you have any of the following then we recommend that you perform the minimum Basic Pre-Dyno Inspection service.
35,000+ miles Check Engine Light (temporary or permanent)
-Any Minor or Major Induction or Exhaust changes performed prior to tuning
