Why are there 30 ft-lb oscillations riding on the torque curve? They don't count.
That might be tie down belt stretch reacting with the car/dyno.
Great looking car.

Seems very low to me as well. Lots of $ for a 100HP gain and loss of warranty. Don

If I were to guess I would say that is the "canned" tune from Edelbrock. We have seen similar results many times with canned tuned... Add a bit of timing and clean up the fuel and the graph will smooth out and pick up quite a bit of power in the process.

This is the dyno graph that Edelbrock has on their website for the LT1 Corvette E-force.
Are you saying this graph is a bald face lie and it does not produce 624 horsepower with their supplied tune?
While not a LT1 a friend had Edelbrock install a 599 HP E-Force on his 100% stock C6 GS at Effingham. After the install using Edelbrock's "canned" tune, it was put on a chassis dyno there at Effingham. It did a 522.9 HP pull. It was NOT dyno tuned to increase the timing or to adjust the fuel.
599 HP at the Flywheel(Edelbrock's advertised claim) and 522.9 HP at the rear wheels = 12.7% driveline loss. Right in line with what LS3's have been producing with the M6.
Oh, and that friend; he owns and manages an auto repair shop that only employs ASE technicians. He and his wife were at Effingham and since Edelbrock was installing their superchargers at the event, he decided to have them do it and then do a dyno run. He does not have a dyno in his shop as he is not a
"speed" shop but a general repair shop for all makes of cars.

In my mind, it has been proven time and time again by several vendors and tuners here and posted dyno results that headers do NOT add any more power on a moderately boosted C7 (7 to 9 pounds of boost). However, if you are running meth and say 12 plus pounds of boost, a cam, etc...; then YES, headers may be worth the additional cost/labor from a power point of view perspective (as no one can argue with the subjectivity of sound).
With GOOD 93 octane fuel, 8 pounds of boost, and with competent tuning, I believe that any of the major centrifugal kits out there (ECS / A&A / ProCharger) will make around 575 RWHP SAE on a dyno jet with a manual transmission; a little less with an automatic. Several dyno sheets have been posted with the aforementioned results.

While I have access to GOOD 93 octane here in Springfield, MO, 99% of the gas stations statewide sells 91 octane. I drive my car on long road trips so it has to be able to run on 91 octane. Since 91 is the accepted octane of premium gas nationwide, Edelbrock has to have the "canned" tune calibrated for 91. I would like to know what a centi would produce if it were tuned for 91, and not GOOD 93 with meth.

I'm sure the "canned" tune with the E-Force is for 91 octane. Now, if you want to change the tune for 93 and meth, then jumping from 550 rwhp to 575 rwhp should be doable with the E-force.
