I ported mine almost exactly one year ago, well before I heard of other people doing it. Maybe I was the first 
.
When comparing REM and Apten I don't think the outlet of the blower will effect things much. I believe the big gains are in the inlet, specifically on the shelf at the outside of the bearings. That's the area I would be concerned about. I don't have any before/after dynoes but I did get at 522RWHP with what I did. It has to work a little bit

Apten has been dealing with ported superchargers long before the Lightning or 03 cobra were ever produced for Thunderbird SC eaton M90s.
For the REM vs Apten, here is the response I put on another board.

I'm sure Razor's edge does a great work on a low cost port job, but we aren't just porting these at Apten, and there's no way that even the porting is identical between the two. I can't show you how ours is done without giving away some of the secrets we spent thousands on the flowbench and dyno figuring out, but there is more than just opening up the triangle on the bottom and port/poishing the top. We have tested everything from modifying rotors to ligher weight rotational componets to come up with the best "bang for the buck". The end result is what appears to be just a "port job" but really we have gone thru the whole supercharger and made the changes that we felt necessary to get you the most power improvment without sacrificing performance, drivability, or durability. We also do go thru and check each bearing and seal to make sure they are good. You would be suprised how many bad seals or bearings we have seen in the last 50 lighting superchargers we have modified. In total, we have 8 hours of labor in each supercharger. If we were just having people send in bare cases we could have a machine do the porting and have half of the costs in it and be able to offer a raw porting for $295 too, but we decided that if we port it we are going to do everything else we can to check the whole supercharger and make it the best we can.
So if you have a brand new supercharer and you just want a $295 port job to get you the 20-25HP people have been posting, Razors edge is an option. Apten won't ever be the "lowest price" game in town, what we do try for is for a balance between the best possible price while still mainting somthing that is of top quality.
The final way to illustrate this is to look at head porting. You can pay anywhere from $600 - $3500 to get your heads ported. Different shops have different levels of experience, and every different place will spend their own amount of time in research and testing. Almost never is the product that produces the best results or has the most amount of time involved in it going to be the cheapest.

I don't know what the differences are but was told by Paul that there is only so much you can port with the eaton.
--------------------------------------------------------------------------------
it would blow your mind to know how differently we feel about that statement. If you saw all of the things we have tested and all of the products that are on the bench being fabricated for our next batch of tests, you would know we think differently
Magnum powers/JDM is another company that I believe feels the way we do about development for the eaton. There is a lot of room to grow on these.

Just because someone does it doesn't make it a HUGE gain. I have seen the Apten outlet too btw. It does look like a lot of work went into it. Does that mean that letting the compressed air escape the rotors earlier makes a HUGE power gain? I don't think so. A slight gain, maybe... but not HUGE. Everyone has an opinion though.
The inlet though is a different story. Taking off as much as you can on the shelf and reshaping it I do think makes a HUGE difference. It allows more air to enter the rotors to be compressed. Apten_tech mentioned Magnum Powers. They moved the rotors up and they made a lot more power, ever wonder why? And have you seen their outlet? Or the Kenne Belle or Works for that matter?

there is no doubt an advantage to moving the rotors forward and making it a rear-feed supercharger like Magnum powers did (and works and KB). We are testing some additional methods to accomplish this, but by just removing material up there you can only do so much to fight this problem. You can't weld up a heat treated case either because it will distort all of the clearances.

think about this. when you have a small opening in the outlet, you have a small area that air exits your supercharger and enters the intercooler. When you enlarge the surface area you are now reaching more of the intercooler and cooling down the air charge more.

. Also I have to say I think Apten is doing a great service for the Lightning community. It's awesome that you are doing all this research to give us more choices in making power. If I was going to pay someone to work on my blower they'd probably get my business. Nothing against REM either. I'm a happy customer of theirs. Just think Apten is really dedicated to trying to max out the Eaton, which I like.

We get quite a bit more out of the bottom. This is one of the times I really want to take this deeper into tech discussions, but we always have to be careful not to give things away that other companies could rip off. In the bottom of our lightning outlet there is a second hole. It's placement and size are critical, because you have to modify the bottom of the outlet in such a way that you do not weaken the case.

Eaton Supercharger Porting
I'm definitely looking foward to Apten's service for porting my Eaton Supercharger. With Apten's experience history, research and dyno proof, I am no longer skeptical of the quality of their service.
I'm attempting 500+ rwhp and 700+ rwtq on the stock block very soon. These numbers will be achieve with Apten's ported Eaton Supercharger. Will keep everyone posted.
467 rwhp 688 rwtq (stock block with bolt-ons)
#1690 of 4000
