The combo sounds like all the bases have been covered. A cathedral port setup should make in the 550/510 range (as stated above) so if the L92 does not hit those numbers, it will be disappointing. If it exceeds that, then it was money well spent.

110 LSA scares me, and I'm fearless
Seriously though, I think the narrow LSA cams with big intake valves are a bad deal. It seems it would make more torque, but run out of breath sooner, so if it peaks sooner then the other graph, you will know what happened. I hope I'm wrong.

We stopped after the 3rd pull at 533 RWHP SAE. I will be getting the leak fixed today and hopefully getting back on the dyno before friday and post up a new dyno graph.
how could a post 02 sensor exhaust leak mess with fueling at all???
50% more fuel??? thats alot more fuel dude..... lol

if it was getting tuned they could have just left the car in open loop and finished the tune, plus at WOT o2s arent working so you could have reset the trims and been ok. Either way you werent seeing 50% more fuel, max on that bank during WOT would be +25%.
Sounds like someone is just trying to make some more dyno money

the only thing i can think of is that they are tuning with a wideband in the tail pipe... if they are then the car can suck in air where the exhaust leak is at and give false readings to the wideband sensor.... highly doubtful... but could happen
how exactly they know the one side has more fuel than the other if they are tuning with a wideband is beyond me... maybe they are running two widebands, one in each side just after the collectors??
