Word around town is that it is a little conservative...I will definitely post up some time slips when I get it taken down to sacramento with the new rear.
I should have a new scan log uploaded tomorrow so we can check out the data. I added the Dynamic Air Cylinder to my scanner.

I've got to learn to be. I cant afford to pay someone 4-500 to tune my car every time I change something. And at my rate I'll be changing a lot of stuff so I'll need to be able to change everything on my own. Plus tuning yourself gives you some self satisfaction.

Also make sure you check the 3/8" pushrods cause mine were rubbing the head bores on my 215 TFS heads...iirc it was the intakes only
I think you need to swap out those roller rockers for a stock set with trunion or get some yella Terra's...those valves have the most weight and I would not recommend anyone getting tfs heads to not get them swapped out...every graph i see with as cast 220 or Cnc 215, etc all has drop offs...

I may have been the first on the internet to post up results with the As Cast TFS heads, and have no problems with valvetrain control with them in many different combinations, you just have to know what works with what. Thats the problem with the flavor of the week cam lobe stuff thats taken the LS industry by storm, everyone looks at a lobe catalog and becomes a "valvetrain engineer" Whats funny is the stuff that generally makes the most power with our setups, are lobes that have been in the catalogs for 15 years. Alot of the newer stuff is just very aggressive and looks cool on paper. Sometimes taking a step back will end up making more power with a happier valve train
