ECU Shootout

Find a dyno tuner for your ECU

A new ECU is only as good as its tune. Every shop here has its own dyno and tunes aftermarket engine control units (ECUs).

How shops get listed

Every shop here has two pieces of evidence: it tunes at least one aftermarket ECU brand, and it has its own dyno. The evidence comes from the shop's own website, or from the ECU maker's dealer list plus a dyno maker's shop list (Dynojet, Mustang, Holley). A ✓ next to a brand means that maker lists the shop as a dealer, so you can buy the ECU there too.
