Can you post the before/after numbers? The numbers on the graph are hard to read. I can see solid gains throughout though. 600 RWHP with cathedral port heads is awesome!

Nice gains, especially considering that you used the stock 90cc throttle body on both manifolds.

Will be testing the 102mm TB as soon as one arrives. I have several on order.
This combo made 600rwhp/560rwtq thru a factory 3:42 gear... Adding the 3:73s knocked 10/10 off peak #s... Looks like the 102mm LSXR bought it back up to par

Drivability is suprisingly good. It needs a minute to warm up in the morning, but after that there is no surging or stalling. I've driven it from Atlanta to El Paso, and take it to work when it's nice. It could be in a daily driver if you had that kind of money (tickets, gas, tires...). This motor has been rock solid for over two years now with MANY top end runs. Can't wait to see how it feels on spray.
The wheels are actually 19's, they just look big.
Everyone may not like HREs on a C5, but I'm happy with them.
