The fact is we already go to Maxton, El-Mirage or Bonneville "pre-tuned"
anyway. So why not see if the run was up to expectations. That way you can
adjust for the next run. Would imagine we have all gone back to the pits
after a full run wondering if a timing change, valve adjustment or cam
advance/retard would make an improvement. Of course any speed improvement
would tell you if the results were worth it, but the in-car-Dyno will give
you a TQ & HP curve that represents where the improvement occurred.
If I had the bucks I'd put one in my car in a heart beat. This comming
from a guy who could'nt make his EFI run much over 150 MPH at Maxton last
week.
