Also the temps are not staying up once the car starts moving and even with the body on and doing a few blasts temps never go over 200-205. Runs well as far as I can tell. Probably running a little rich up top?
At this point in the break in you can start to lean out the top end slightly each tank or so. This in turn will give you more heat and slightly more RPM. Heat is absolutely essential to a perfectly broken in Novarossi. You will also notice the motor will go rich as it starts to break in more and more. Keep at it you have a long way to go till she drops.
As far as the VP goes, I run the 25% VP Powermaster and I really like it. The race blend will render more power but you also are taking out a good percentage of oil. A lot of people I've talked to run the 25% VP with an ounce or two of Klotz Benol. I run the castor oil in the VP as well. Little castor oil adds a safety net. Id start with 2 oz if you are newer to tuning to add a little safety net in case we go a little too lean, or if you are comfortable with tuning try 1 oz.
