first of all I am in two minds about tuning my C20XE, basically the block is been fully rebuilt at the minuet, with a lot of work on the bottom end and head, now we can either for twin 45's or TB's, so what I want to know is, as the TB's are a considerable amount more expensive, do the benefits out way the cost????
How much more do TB's generally give over 45's??
Also which cam is preferred/most popular when running
A, throttle bodies
B, twin 45's
