I have the Stage 6 port. I'm impressed with the way it pulls on a 2.76 upper only, compared to a stock Eaton with a 2.76. Has a substantially louder scream in the summer too, compared to stock Eaton with a 2.76. Major power improvement and pulls so much stronger than before.
I have about 30k on my stage 6. Trouble free and I'm anxious to see what it can do in the future with a 2lb lower.

Had the stage I, III, and IV on my car. It got faster every time. They had a winter sale every year that had a special on upgrades.
Do you have any dyno or track times to back that up or was it a seat of the pants improvement? I'm asking because I have a used stage 4 that I'm going to have refreshed and was wondering if it was worth it to upgrade to a stage 6.
i bought my cobra with a stage 5 port so i dont have anything to compare it to...but 491 RWHP is very nice 
for now...lol
for now...lol

I have no experience. But just by the way they consult their business, being a business man I believe they do pristine as-well as take pride in their work.
It dynoed 465/485 with the stage one package from Apten with a 2.80" upper and Steeda catback, but the flash tune was rich. It was retuned on the dyno by the owner of Apten at 490/490.
Herman street tuned the stage III upgrade along with 4# lower, 60# injectors, BAP, ported/welded plenum, ported TB, MRT-H and SCT 2600 MAF. They estimated 525+ HP and TQ. It ran consistent 11.70s.
The stage IV port, with all else being the same but JBA shorties, brought me to the 11.50s consistently. I granny shift and use MT Street Radials and never saw a faster 60' then 1.7x with that setup. I would slip the clutch off the line around 3-3.5k rpm.

Mine stage 5 put down 520
I have a steggy black plaque on the top of the sc. Just with i knew what stage it is. I currently have 470whp with pully, longtubes, full exhaust, port, bbk cai. and tune. Car pulls hard but really have nothing to compare to.
Look at the stamped # at the base of the SC in the front (I think it is on the left). Call them with the number and they can give you the stage and service history.
if you wanna make more power later.. don't waste your time.. I have a stage 5 and regret getting it done.. not because the lack of power , but because the limit of power the blower can make.. My 2 cents.. save up and buy a whipple or TVS...

Comparing a ported Eaton with a t/s is just silly. And the price difference is quite significant for some. And that's not even considering the fuel system upgrade that's required with a t/s.
Had a stage 3 years ago from them. Stock lower, 2.8 upper, magnaflow exhaust, k&n intake, stock plenum, tb, and manifolds. Made 493hp, 501tq, went 11.5@122, added 2# lower and went 11.4@124 full weight (3980#)IRS. Seriously for the little money you can spend to go mid to low 11's a port is worth it.

If your running a ported blower with a 2.76 upper your going to be maxing out the maf and getting very close to maxing out the pumps and 39lbs injectors... yes a TVS is more expensive.. but as stated before, depending on what you think you want to be horsepower wise, if going higher than 550... just skip the ported blower... wish I would have...
