Required. Customer must supply their own wideband O2 sensor and bung. This is not provided by JNOS.

  • New spark plugs, gapped to spec. Johnny will confirm your plug type and exact gap after your deposit is made, based on your mods and application
  • Oil, coolant, and transmission fluid topped off
  • Tires in safe condition for dyno rollers
  • Boost leaks checked (turbo/supercharged cars)
  • Battery in good condition
  • Sufficient fuel level for the session length

Vehicles arriving without these items completed may require additional shop time, billed separately at Johnny's discretion.

If Johnny has to gap your plugs, that's an extra charge starting at $50 minimum. 8th/9th-gen platforms carry an additional charge starting at $50 on top of that, for the wiper cowling removal and extra labor those platforms require to reach the plugs.

gavel Booking Policies

Deposit & Cancellation add

A $150 minimum deposit is required to confirm your appointment and is subtracted from your dyno session cost. The deposit is non-refundable except for a legitimate emergency. If you have a real emergency, your reschedule date is at your discretion. If you simply don't show up, Johnny will select your reschedule date, and if you miss that appointment too, the deposit is forfeited.

Rescheduling add

Changing your date requires a minimum of 3 days' advance notice. Don't wait until the last minute. No extra charge to reschedule if you give at least 3 days' notice and a slot is available. If no slot is available, Johnny will give you the next day and time he can fit you in.

Late Arrival add

A 30-minute grace period is allowed. After that, a late fee of $25/hr applies.

Scheduling Lead Time & Daily Capacity add

Bookings must be scheduled at least a week and a half in advance. To keep every car getting real attention, JNOS takes a maximum of 5 cars per day on the calendar.

Walk-In / Non-Appointment Tunes add

Walk-in tunes without an appointment are $700, and only happen if there's room in that day's schedule. It depends entirely on what's already booked. If there's space to fit you in, it can happen.
