called the shop while in Atl yesterday to see if they had time to tune my 09 P30...guys were friendly on the phone and very accommodating...i was in town for a conference and wasnt getting out til around 2pm but they said come on anyway....Thomas out front was great to deal with(even though busy as hell!!!)...Tony (tuner) answered all my original questions on the phone and all of my new questions i had when i got there around 245...took my car in the shop, applied their tune, test drove my car to check for any kinks and then turned me loose...price was more than reasonable and my cheap *** still left with a smile on my face....now my impressions of the tune......

being as it was late in the day and i was a work in appt they didnt have time to tune on the dyno(which i completely understand plus my car is basic mods so their ready made tune should be fine)

i really wanted to call bs about the posts where people said that their cars "sounded" different after the tune...so i fired it up in the parking lot and ill be damned if it doesnt!!! not louder so to speak but definately MUCH "throatier", meaner, deeper.

pulled out of the parking lot and IMMEDIATELY noticed that the tranny felt WAY different than before...shifting is firmer, faster, seems to downshift at a higher rpm than before(god you cant help but love that throttle blip), and upshifts faster as well....(the tranny changes alone are worth the price of admission)

as far as power goes you can definately feel that there is more available even off idle but where you can really feel the difference is when you go WOT and hit about 2500rpm...from that point on it is a freight train!!! very impressed with the gains and im hard as hell to please

on the interstate on the way home the difference was obvious as well...whereas before if the cruise was set on 75-80mph and you needed to pass or blink and merge you actually had to give it a little throttle to get her to move on out, now though, all you have to do is touch the pedal and the car lunges fwd without any effort, i loved this!!!!

trip up to atl is about 180mi with the last 100mi all wide open, 4-6lane interstate...drive up had the cruise set on 80mph and got 21.4mpg...same stretch on the way home yesterday with the tune installed and cruise once again set on 80mph i got 23.1mpg...gravy!!!

all in all i was not only more than pleased with the tune and the car running like she was designed to but just as much in the way that the shop staff and service was a great experience in its own right.

Great work guys and I'll keep coming back for more!!!!

posting a link below for you guys to review(if its permissible with the mods)

B.I.P. Tuning by Tony

Correction factor for their Dyno Dynamics unit is set at 0 so you guys can begin your Mustang, Mainline, etc. peak #s comparisons as I'm sure will ensue but I can honestly say that I am MORE than pleased with the end result....Freight Train!!!!

rentzington

having a bit of a hard time reading the dyno on that, but was it 389?
no offense at all, but i would have expected to be in the 400's at the wheels at least.

all that matters though is you are happy and notice the difference by the buttdyno

did you happen to get any dyno's before your exhaust mods? i'm kinda on the fence about those.

jptaylor

It is indeed 389rwhp....I really wish some of the dyno gurus would chime in on this to add some insite but here is what google has told me....Dyno Dynamics and Mainline typically yield lower #s than other dynos. The limited info I could find was that it was not uncommon for DD and Mainline tuners to set the correction factor at 1.13 when there were other brand dynos in the area so that the #s were more in line. If you take that into account then my 389 would SEEM to have been closer to 435-440hp on others(ie Mustang) and that seems high to me. But as for buttdyno there is no doubt I have reason to smile like a jackass in thistles! !!

deadfission

Yea. BIP doesn't have that factor corrected in. I dyno'd at 393 on mine with just a tune and kept seeing other people dyno in on the forum at like 415+ with just tune. Talked with Jason and he told me all about the factors and dyno scatter. I'm happy with what I got and you can extrapolate your crank HP if you assume it being a perfect 451 at inception and its original dyno run. Everyone should be around the same.

rentzington

Unfortunately i'm not up on the various dynos but if what you are saying is correct it makes sense it would be 435-440ish as most people with tunes from eurocharged are getting 420+ at the wheels with just a tune.

the shop near me has an awd mustang dyno, i need to finally move my butt and set up an appointment for a few runs.

choppo

I am going there in the am tomorrow to get mine done as well. Will post my results here as well.

deadfission

Where the hell were you clowns when I was complaining about the lack of AMG forum members in ATL and wanted to have our own cool meetup like they do in Cali & TX!?!?!?!

jptaylor

Being as we are rated at 451hp and the E/S/R/etc m156 engines are rated at 507hp then the retuning of our tables theoretically "should" be able to get us to at least their level of rated power output....with the engines being internally identical I have no reason to believe otherwise. If the tuning gets us to 507ish then the tuning with mods in place should result in optimim output for that engine with those mods. Here is what my google educated math would seem (very loosely) to indicate.

389hp x 1.13 CF = 439.57 standardized wheel hp

Then

439.57hp x 1.21 (21-22% parasitic loss) = 531.87 flywheel hp

I thought that these were high on face value but if the end result is even CLOSE to the same way MB rates the m156 by their standards then the numbers may actually make sense.....507hp stock to 532hp with minor mods and tune doesn't seem TOO out of line

choppo

Well this clown is in for a meet.

deadfission

You don't happen to have that white E63 that was turning onto 285 from S Atlanta yesterday, do you?

choppo

No, I met that guy yesterday at that shop yesterday he had a paramedics or doctors emblem on his tag.
I have a 2010 grey c63.
Said he was attending a meeting somewhere up in buford and since he was kinda close to BIP he wanted to get something done there on his tune is all I know.

deadfission

O nice. Legit. Well I have a black/black 2010 C63 as well. I live right next to BIP (literally i can walk to it) so if you're out there and you see me being a dick, just wave and say hello!

choppo

Ok LOL.
I just live like 10 minutes east near 75/285.

jptaylor

I am the one with the white p30 with the paramedic tag...choppo and i met yesterday when i was at BIP to have the dyno runs/revisions made....great looking p31 car by the way


and HOW DAMN BAD was traffic yesterday??? my god!!!!!

choppo

Traffic SUCKED bunch of damn rubberneckers !!

Looks like your happy with your tune , i would be

I just hope my tune turns out as good as yours did.

jptaylor

Forgot to add....

Torque was 377 peak at about 3800rpm

and

AFR was nice and flat around 12.5 which was comforting

choppo

What were your numbers before you tuned if you can recall or remember ?

jptaylor

Unfortunately they didnt have time to dyno me before we did the 1st tune...so all I have is the after dyno....MEANING, you could get us a baseline run on your car so we could have some apples to compare to....wink, wink

choppo

lol thats what i was trying to find out without doing that , wink wink back at ya

jptaylor

Touché

jptaylor

alright Choppo, don't leave us hanging!!!!!

East Alabama checking in here. I am contemplating working a deal on a 09 C63 this weekend or next in Atlanta. I drove it several months back but the paint was in to rough of shape for the original asking price IMO. Now they are getting close on what I feel the car is worth.

Glad to see there is a place within reasonable driving distance to get a tune.
