Anyone hear of Jone’s Cam’s
I spent all day yesterday talking to a german tuner. I learned alot about our cars and depending on factory ECU firmware makes a difference on tuning.
My firmware didnt have the option enabled to change in vidiamo and the us vs euro firmware is different. That's why our fuel trims are wack with row boxes etc.
Same tune on eurospec black series firmware will make more power.

Really that’s interesting. I had the same fuel trim hunting. I fixed it all with HPTuners.

Awesome keep us posted and depending on the specs of the cams they could likely benefit the supercharged guys as well.
Will do brother and yes it most certainly would help the FI guys!
Amg has bigger cams on the sls black series but they upped compression ratio and changed the final drive and the car LOST power under the curve,it has lower torque and a way higher redline .I think its 7900 and can rev to over 8500.
They also have velocity stacks inside the intake manifold to speed up velocity to help part throttle and mid range torque.
I'm afraid you will end up spending alot of money and not be happy with the results.
You are a perfect candidate for the sls intake with the regular sls cams. It will lose a little down low but make 577 crank hp
Again the cams are out there and amg already made them for you.but I honestly would not do it on a street car.

the loss in power is on the spec of the cam. While the m156 and m159 share similarities deep down there are different.
A set of our Billet Steel cams for the M-156, is $4,400.00 + Shipping
Here's the 2 options I would look at.
H68475-67440: Intake 228@.050" with .475" Lobe Lift. Exhaust 224@.050" with .440" lobe Lift.
H69475-68475: Intake 232@.050" with .475" Lobe Lift. Exhaust 229@.050" with .475" lobe Lift.
We have gone as big as 255@.050" with .500" lift, but I think that required a lot of other changes to the engine.

We are slammed right now, so I really don't want to get into dealing with a group buy, at this time.

Thats all the info I got. I’m not sure on the stock specs and not sure the valve buckets can handle that lift... may need to upgrade to sls black series buckets... maybe someone who knows more will chime in?
if anybody has a spare head, any head porting specialist could measure out the entire head for clearances, spring pressures, spring heights, bucket pad diameter, etc. that is what we'll need before we could even think of what camshafts could fit. along with this, we may need to permanently lock out the cam adjusters if the cams are too big.

You are right. At the cost to do all that crap you can throw a weistec stage 2 and be done with it.
