I was very skeptical of Dinan's results big time !
And despite of this, based on this forum and other forums i pulled theatrigger on Stage 2

I have videos for your reviews and comments!!

Observations::::::>>>>>>
#1 using my butt dyno it is a lot faster than stock, actually in a scary way!!
#2 Power is all over the RPM but more so after 2500 i guess, and I am no expert
#3 i hate my Dunlop Runflats, they are embarrassingly spinning with a mere deep push not full throttle even at rather higher speeds like 30-40
#4 No regrets 100% Worth it no doubt
#5 Never took videos before as numbers were consistently embarrassing like 6 and very rarely 5's so didn't bother but now I need your help Experts, how fast ate these videos? Put in mind I am absolutely no expert, I love to drive but don't race!! I just wanted to see how fast it is, but ended up with videos that I can't seem to interpret and I need an expert eye :)

#6 Price 3350$ Stage 2

#7 By the way, what is a bad high temp of this engine, because got close to 250 f after a few runs!

Thank you guys,,, I really think it is that fast

I test drove CLS63 2012 PP with matte pallidum silver MSRP 122k a very rare launch edition, but was used with 12 K for sale and,,,, please don't call me name,,,, didn't scare me like this!!!! May be the fact the the dealer CA was with me made me not push it crazy!!! Most likely as I know 3.7-3.8 !!! But still this 550i is Very close !! Actually also test drove CLS550 without console shifter and despite of C&D 4.2 clocked 0-60 yet didn't feel as fast at all!!! And I test drove it alone that time, as I had MB and the dealer knows me,

I had E550 coupe 2010 NA 5.5 fast and supposedly 4.7 by C&D and felt like a turtle compared to this mighty 550i Dinane 2 !!!

Good job Steve Dinan

Still makes me smile !!

This car has become crazy fast which is still an understatement! ! The torque being 580 is the reason why I feel so! !

I had E550 coupe which per C&D 4.7-4.9 sec yet was nothing and felt nothing like this beast! ! And i Never felt it was!

Not surprising at all to me if 0-60 3.9-4.6 range

AndI am saying that after test driving so many fast cars, for instance I test drove Porsche Panamera S just
A few weeks before this, and liked it but never surprised by its speed and actually felt as fast as my E550 2010 NA 5.5 engine which was sub Five 0-60 times per most reviewers ...

And stock 550i when i got it and drove it for well over a week felt a little faster than my E550 and may be the Porsche Panamer ORa S 2010,

YET
After Dinan Stage 2:::::::::>>>>>
OMG
It is freed of its captivity :)
And getting better day after day,
Sometimes I would experience some Turbo lag but may be one out of 10 times when I push hard, because I push all over the power band and the RPM trying to see where and how and when it works!! !

But still even a few days after having it,
Everytime I push it I feel that it is a BOMB EXPLODING, OR AN ARROW or crazy crazy fast.... and I have no idea why, I didn't have this feeling in faster cars!! That I know are faster and have more power like CLS63 AMG 2012 5.5 Biturbo 550/590!! !

Can anyone tell me why?
And in particular CLS550 2012 supposedly 4. 2 sec, yet nothing like this Stage 2 Dinan 550I M Sport 2012, and I test drove it alone and I really pushed it hard And was fast but not surprisingly fast especially comparing it to my E550 coupe 2010,,,
And i even owned G37S 2012 which is clocked 5.0 sec but was like a turtle compared to this mighty 550i after the Dinan.

HAHA. I share the sentiment. As another user has posted, I'm enjoying the Smiles Per Mile (SPM). Dinan stage 2 is tremendous, I hope I don't face any error codes with the AWD system requiring a re-flash.
