Default ***LMR LS7 CNC program picks up 35rwhp!!!***
Grey brought us his car to do some testing on our brand new prototype LS7 cnc program. Made 2 pulls, pulled heads off, installed our ported heads. Made 2 more pulls after a finished tune. Car ended up making 581rwhp through the stock intake manifold and throttle body!! That is within 5rwhp of a well known aftermarket casting ls7 headed/Fast102/102 ls7 we did a while back! Call us today to get your heads CNC'd today!

Here are the flow numbers. As you can see our numbers are lower than most other programs, but yet we've made more power with these than all the other CNC programs we've used (for ls7 heads).

Lift Intake Exhaust without pipe
.300 237 146
.400 295 181
.500 345 204
.600 377 225
.700 387 240

They Dynoed my car when it arrived three times. Never got over 548.

Drove the car to dinner... Runs great and I leave tomorrow to go do the long haul on the hot rod power tour!
