You'll like the Quaife. it at least forces both sides to let loose before youstroll along, so it minimizes ESP kick in.

WOW!!! Those are amazing numbers.
Renntech states their Stage 5 makes 521 TQ on 93 octane fuel. And you're
saying your car is making that on just a pulley and California fuel.
I'm getting ready to pull the trigger on a stage5 soon, so can someone please explain this. Thanks.

Those A/F ratios on Jay55's car are SPOT on. That is how the code is written. The car will dump fuel from 5.5k to 6.5k to make sure you run rich enough to not risk burning the motor. The renntech C32 does the same thing and is around 10.2 from 5k and up. On our car some dumb dyno tuner told us it was running way lean and that we could be hurting the motor. So we installed a wide band o2 sensor into the exhaust and put a gauge in the car. Turns out the car ran EXACTLY as Oliver had said it should. Dont worry its all just right on Jay55's car.
You could maybe lean it out a bit to gain a few hp but its not worth the risk involved in damaging the engine. They give you some power but also make sure you will not risk the motor.

Thanks for enlighten me with this whole dyno ordeal. PSK145 and myself are concerned about our rpm peaking at 5200 instead of 6000 like other dynos posted on here. Even my stock dyno chart peaked at 6000, should I leave the ECU the way it is or have Renntech fine tune it?

Jay: another thing about your top end could be the added heat you are now generating. If the temps get higher, the system will "dump" fuel to protect it. The fact that mine runs so rich is exactly why I am not messing with the ECU for now (that plus I still haven't seen '06s getting gains). I'd like to see your top end with an IC upgrade and headers.
Glad you are up and running well. I just wish I had my old beast back.

I have a Stage 5 and my dyno results were very close to the posted R/T results. I dyno'd 484 rwhp and 542 tq. I think the Stage 1 numbers are strong so if you're looking for "bang for the buck" I would stick with Stage 1. With Stage 5 I now have I/C cooling issues so I'll have to invest in an upgraged I/C pump and heat exchanger.

sorry for sounding dumb (probably means i am 
)
iam from UK, what does the Stage one include from renntech ?
what is the base power you are acheiving/finding on a stock e55 amg on the rollers at the "fly" < (not wheel) and what is the stage 1 power at the "fly" after this stage one package.
just so i can get my head around the figures.
sorry to be a pain (and no i wont say old bean
)

)I do not know about "fly" numbers as you'd have to have real concensus on what the drivetrain is draining from the power. The dyno literally measures the power at the wheel, so that is the number I track.
I would consider most E55s to run about 410 - 420hp (at the wheel) in stock form.

417 damm thats alot better than mine did, it was only 401 for me stock. then 447 on renn stage 1. you went 417 to 461 =44hp i got 46hp. so our tunes are about the same in hp gains but yours kills mine in stock form. get the i/c upgrade and keep all the power ready for when you need it.
