Looks like a fun setup! I realize that dyno numbers are not everything, but I figured you would have made a little more power considering you have ported heads and a cam. My centrifugal SC made low 600s with similar mods minus my heads being stock 243's. I do like your torque curve, but I figured you would have made closer to 600whp.

I'm very pleased with the results and with the dramatic change the blower and the rest of the mod's. have made to my car. I've put a little over 200 miles on it since getting it back and haven't experienced any issues. It's been very hot here for the past 2 weeks and the car runs a little hotter than I would like so I'm having a new DeWitt's radiator installed on the 20th. I'm still a little undecided about my new exhaust. The car sounds great on the outside, but the volume and the resonance on the inside can be a little overwhelming. This is my third aftermarket exhaust and it may not be my last.

My blower only GS is within 20 HP of him thru an A6, and I make WAY more Tq. I can only hope that his converter is that sloppy, or the tires were slipping on the dyno.

Post your dyno sheet and mods and lets discuss or better yet let the builder (Livernois) tell you why you are trying to compare apples to prunes.

So basically it looks to me like the Eforce is a dud.

If Mike, or Doug still have the sheet, they are more than welcome to post it up. Bottom line is my car made 530/520 in 95+ heat and swamp like humidity in July with JUST a ECS 1500 kit and their tune. Not to mention that there's a stick GS with the same exact setup that I have that makes 570/560.

I'll agree with that. That's pretty much why I was pointing the finger at the torque converter being sloppy/inefficient, or maybe the car was hazing the tires on the rollers. Either that, or the ECS guys are way better than I give them credit for. I like the curves, but they do seem low to me.

Most of the LS3 Vette guys going for as-is bone stock + E-Force are seeing around 525/510-ish on 6-7 lbs of boost. FYI the OP with the original dyno sheet in this thread is running a hybrid setup on a 2006 LS2.
FordRacer9 back on 26 July you announced (without a dyno sheet) you made 530/518 on your GS....pretty similiar numbers to the Edelbrock although the E-brock's torque will come in much earlier than a centri. The OP's 4 year old LS2 made 565/496....I would not count 22lbft of torque as "Way More" and it looks like you are 35hp shy of his mark rather than the 20 you claimed. This 4 year old LS2 will spank your new GS all day long!

I still say that I like his curves, but do beleive them to be low. Might be the dyno, the trans, the tires, the tuner, or a combo of them all.
Stop defending just because you sit the same as him, yet you've never gone to the track, or even put it on the rollers of a dyno.

Man I sure hope so! How can you come on board this thread and bash the results of one of the best known shops in the country when you've never tuned an LSx and don't even know what your own car's performance looks like on the dyno?
