Custom GM builds · LS and LT · Frankfort, Indiana
Specced, built, degreed, then tuned in the same building.
Corvette · Camaro · CTS-V · Silverado · Sierra
A cam is only as good as the calibration behind it
Plenty of shops will install parts. Fewer can pin an ECM, fewer still can tune what they built, and almost none can put it on a hub dyno afterwards to prove it. Doing all four in one building is the reason cars come here from Lafayette, South Bend and further.
01 — SPEC
Parts chosen for your combination
Cam, springs, pulley, injectors and fuel system picked together. A cam that fights the converter is a cam that costs you power.
02 — BUILD
Degreed and assembled
Measured, not assumed. Clearances checked and documented so the tune has something honest to work with.
03 — CALIBRATION
ECM pinning, where most shops tap out
Pinning, flashing and custom calibration on cars other shops send away. This is the capability that makes the rest of it possible.
04 — PROOF
On the hub before you leave
Baseline and final on the same equipment, same day. You get the sheet, not an estimate.
What we work on most
Late-model GM is the specialty, but the dyno and the tuning do not care what badge is on it.
C5 / C6 / C7 / C8
Corvette
Cam packages, blower and pulley work, supporting fuel, and calibration to match.
5th and 6th gen
Camaro / CTS-V
LSA and LT4 ported blowers, pulley upgrades, heat management, tuning.
LS and LT trucks
Silverado / Sierra
Cam swaps that still tow, AFM and lifter work, tuning for the way you actually drive it.
Questions we get asked
What does a cam swap cost?
It depends entirely on the combination — the cam, springs, and whether the calibration is included. We spec it against what you actually want the car to do and quote it before anything comes apart.
Is a tune safe on a stock bottom end?
Usually yes, within limits. The risk is not the tune itself, it is asking for more than the fuel system, cooling, or converter can support. The honest version of that conversation happens before the work, not after.
Do you tune as well as install?
Yes, and that is the point. Plenty of shops install parts and send you elsewhere for calibration. We spec, install, tune and prove it on a hub dyno in the same building.
What is ECM pinning and why does it matter?
It is unlocking a computer that is otherwise read-only, so it can be flashed and calibrated. It is where most shops stop, and it is the capability that makes everything downstream possible.
