24-valve 5.9 Cummins performance questions, answered.
Will a tuner hurt my VP44?
Not if the fuel supply is healthy and you watch fuel pressure and exhaust temps. That’s why we do the lift pump and gauges first.
Are your upgrades street legal?
We install emissions-compliant parts and don’t do deletes.
Do you install at my location?
Most upgrades, yes. We come to your home, shop or job site around Tucson.
