I had no baseline done. I wish I would have so I knew what I really got from the tune. The car does feel a lot stronger now. I really was most concerned with correcting the speedo after I changed the axle ratio last year(3:42-3:73). I figured if I got some extra HP out of the deal, great! Any way you look at it a dynotune is $450-$550. I could not fix my speedo for much less anyway.
I guess that without a baseline there is no way to measure what I gained.
The main question is- are my numbers good for a lid and a tune?
I do have almost 100,000 miles on the clock.
I am happy with what I had done, except I was really hoping for over 300 HP.
Z98- Is it not possible that between the lid and tune I am up 25 HP??
