Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.

So his customers are happy & your only theory is a happy dyno.......good job !!!!
Yes. I have no beef with that, we all have to make a living, just that an AFM L77 @ 5150rpm (auto 4th gear std tyres @ 196kph) does not gain the claimed increase in Volumetric Efficiency from bolt ons and recalibration to make 270rwkw.
It is not my theory or guesswork, engine needs more rpm, lift and duration to generate more hp from increased CFM, there is no magic in the physical mechanics of an LS.
FFS man read some more, I'm telling you some potentially valuable info directly from first hand experience.
^^
Haha Sonny!, my case in point, good example, thank you!
Been there several times OTR, ECU, full system, tranny tune, framed chart... good service. But suffice it to say his dyno is happy hence a lot of customers are too.
Good on him, I've moved on from that, anyone promoting 270rwkw from the increased VE of an L77 at 5150rpm solely via artistic expertise in setting dependents for PID calcs on top of the branded brilliance of bolt-ons (while retaining AFM L77 intake and top end) is having a lend.
Install a custom manifold, ported TB, increase the lift, increase octane, alter timing and raise the injector cycle during PE on dyno to suit the low KR characteristics of ethanol, beef the valvetrain redline with indestructible nitrided springs and stronger moly rods and hey presto 270-285rwkw maxing out the L77 cam lift / duration limit @ 5650rpm.
Only then you see the need to crack the engine open and install a better cam. Or VVT.
What makes you think that anyone is actually going to believe you, over the constant evidence and testimonials of customers who have visited one of the most well known LSX related performance workshops in Australia?
A friend of mine who also happens to be my mechanic (when I need professional work done) works closely with EFI dynamics out in Lilydale, his dyno and tuning yields very similar numbers, and hey, so does APS in frankston, LSX in Hallam...
They all happy dyno's too?
Why is everyone constantly objecting to the blatantly obvious facts out there!!???
The numbers are what they are. Tunes are worth the money and unlock enormous untapped potential from massively detuned motors (not talking just Holden/LSX here) etc etc etc...
This thread is so much better in 3D
I just want a good setting for 91 ron, and that's how my car will always run as I don't plan for cams or blowers etc!!
