I tracked down the specs for both cams. There are differences.
Stock arm intake 196 deg exhaust 208 deg intake lift .478 exhaust lift .466 LSA 116 deg
L96 cam intake 193 deg exhaust 200 deg intake...

Actually Lean of Peak (LOP) does the opposite of what Alvin mentions "Lean until EGT's max..then a few turns back rich??" They actually continue to lean out the mixture until RPMs fall. The EGTs fall...

Well, I screwed up the question. It is actually Lean of Peak.. Again, looking for peak fuel efficiency when running at a constant RPM on the highway. It seems that the engine at a constant RPM...

Thanks for the response. All the LSA and lobe heights seem to be the same between the AFM/DOD and L96 cam. The only difference, I think, is the rise and fall shape of the non-dod cam. Yes, I did...

In the piston aviation world there was a lot of discussion about Lean of Prime fuel management. The concept is that at constant RPM you can lean the cylinders and reduce fuel burn rates without...

Just rebuilt a 2007 L76 and AFM delete and the oil deflector makes all the difference.. problem is that you have to get the pan out!

@SirusC1024 Did you have an opportunity to look at this tune? Thanks!

@SirusC1024 Sorry for the delay. Here is the tune for the 2007 L76 engine with the L96 non-dod cam and all ls7 lifters. Everything else was returned back to original. Thanks in advance for looking at...

ok...

Is that a base line tune that can be used for my 2007 Sub with an...

Hi, This is Rich from Weston, MA Been working and restoring cars for many years. Love it. Just can't make a living at it yet. :-) Worked on and seen many engines over the years ranging from Lincoln...

UPS just delivered the HP tuner! Yeah..Took too long.

Question: Does the hp tuner have a module to run a test on the new cam? My standard OBDII reader showed a bank 1 lean code after running a...

Thanks. So for a newbie tuner, is there a place to enter cam specs in the tuner software? And when you upload to the ECU, will the ECU and HP tuner return based on that?

Maybe I was able to answer my own question...are these the same part? Or are the DOD lobes different and not reflected in the numbers below?

Original L76/L77 cam is Camshaft Part Number:...

Thanks. How does the computer know that the new camshaft has different LSA and duration from the AFM/DOD cam?

Hi Folks,

I did a DOD/AFM delete on a 2007 Gen IV 6.0L (L76) . I used the GM L96 6.0L VVT Cam, use w/ OEM Valve Springs (28-12626660)

Started Right up. Runs on every other cylinder...which is...
