Should I buy HP Tuners or pay a dyno shop to tune my LS?
It depends on whether you want to learn tuning, or just want it done.
- Buying HP Tuners: an MPVI4 interface was listed from $399.99, and credits are $49.99 each (about 2 per engine computer; prices as listed 2026-09-29). After licensing, you can retune that car as often as you like. You also have to learn the process: wideband, datalogging, and entering injector data correctly.
- A remote tuner using your interface: many remote tuners work through your own HP Tuners cable. You log and they revise the file. LSX Magazine's interview with MailOrderTuner describes this as a low-cost option that works for most street combinations.
- A dyno shop: worth it for high power levels and when you want a new combination verified, since the dyno shows mechanical problems quickly.
Want to do it yourself? See who tunes it, and how to learn.
