360 street build, please critiec

Shade... LOL Somebody is grumpy. :) Reality is that back in the early 2000's, it was a FACT regarding westech and supported by the DF article, EM issues and our experience with them back then. Westech got it fixed and is good now.

A sharp dyno operator can do what they want with some of the software factors involved, another fact. If you wish to bury your head in the sand and say that overstatement isn't a possible issue with these "tools" then cool. There are good and bad actors in every part of the testing population. Most are good guys at what they do. Use dynos for what they are and note the changes you make during a session and resulting output. The MPH at the track will help with whether the output was accurate.

Carry on

Sorry about the off course with your thread Greg.

The head is going to be your break point for output. 450 might be a bit tough to hit if the head is choking it.
