I calculated, for
Step 1 - Baseline test (optional) ($50 per injector; 50x8=$400)
Step 2 - Cleaning, Nozzle Baseline Flow and Tip Swap ($90 per injector; 90x8=$720)
Step 3 - Media Hone nozzles:
*up to 30% flow ($374.40 for set of 8 injectors)
*31-45% flow ($468.00 for set of 8 injectors)
Step 4 - Test and Balance within 4% ($728, I'm guessing for a full set of 8 injectors)
for all that, based on their online pricing (see "Services" link posted above)-
30%: $2,222.40
~40%: $2,316.00
and that doesn't include any additional costs.
If you leave out the baseline test (optional), then you are looking at ~$1822.40 for the 30% hone.
