Custom tunes that make your car drive right.
I’m Jackson Jensen. I write custom remote and street tunes for GM LS & LT and Hemi (2005–2012) on HP Tuners — reliability first, then drivability, then performance.

How it works
Most people start remote. If you’re in the valley, I can also street-tune at your house.

Remote custom tuning
You log data. I write the tune. We revise until it’s dialed in. Payment before the first file is sent. Message me first so I can confirm your setup is a fit.
Street tuning at your house
Anywhere in the Phoenix valley — no tow truck, no shop. Most tunes are street tuned. A good street tune lands very close to a dyno tune. Goal is about 2.5 hours; it varies by car. The vehicle needs to be in good mechanical shape (no leaks, misfires, or vacuum leaks).
Why not just chase peak numbers?
A great tune makes your car drive right — not just make a peak number on a pull. I keep limits in a reasonable range and don’t trade reliability for a couple degrees of timing.
