Just to give you some ideas, above are two 2000 ex setups with over 100k on the motors. I coincidently tuned them on the same day. One of the guys was from south Florida, the other was a local.

I was honestly supprised by the y8 with the 230whp.
The y8 with 205whp was not holding boost very well with the manual boost controller.
(I believe it had a boost leak.)
