im skeptical.....

wish they could show some real dyno charts, i can draw those on MS Excel....

id be interested to see real dyno charts though, as this is much more than other chip companies claim.

Hmmm, 19 HP with this www.powerchipgroup.com plus 13 HP I have with my evosport ud pulleys, plus around 10 HP with K&N air filters and AMG exhaust, thats 317 HP! Is this true?
Ben, any comments here. Are this finally the chips everyone has been waiting for?

After reviewing their site, it appears to be the real deal, but that's what everyone thought about junk bonds ? Is it to good to be true ? Does anyone at this forum have any dealing with this company, or the product in question? I am very tempted to buy the chip, but I would hate to have the sucker sigh hanging over my head. Below is a testimonial from a E55 owner :

Customer comments:
I can't believe this works...I just shipped my chip overnight to LA and the following day, I installed it back into my car. Now its just such a fun car to drive. I like to rev it all the way and take advantage of the new rev limit. And the other good thing is, now I can reach my cars maximum speed without it cutting out and hitting the 'speed wall'. Overall, great product, and thanks for the customer service as well...I'll be sure to tell my friends about you guys

Customer Testimonial...

Ummm, duh, i luk 2 sit en muh girage an rev duh ingine too da limitor, sew i kin smell de burnin cylydurs. Reelly cuul!

If they make half those gains, that will be more than any others so far... In reality, you aren't going to get 15+ hp on an OBDII naturally aspirated Mercedes engine.

I don't think those are dynoed numbers by any means, why didn't they work with RWHP?
Besides that testimonial was posted today, after two of us called them and ask about their chip for the AMG vehicle, so I'm not completely convinced that is a true customer, it just seems like a very BIG coincidence that somebody would post a testimonial right after a few inquiries and me mentioning we were talking about them here at mbworld.

I'd be willing to try them if everybody here sends me a check for $20.00 bucks, I'll dyno my car before and after and give you guys detailed info on results (I'll be the guinea piggy)

Mach430

Before you volunteer... I had an experience with another company that resulted with my car running on 5 of 8 cylinders. That is not the key to power gains! Let someone else be the guinea pig

pocholin

Well, after volunteering and surviving Windows ME and Windows XP beta releases I feel i can survive anything
But you got a point.

theine

What a shame, because the company looked very professional, with outlets around the world.....but to spend 900 bucks and have your car run in 5 cyl, I can do that for free.

amgme

since you have 14 days to return the chip, you should just run it a bit before dynoing again. my 2 cents.

pocholin

Great, i just talked to them about it, and they say they've done it before on AMG engines and that there is a nice difference you can feel, I'll probably do it in a couple of weeks, I even asked Travis if I was going to be the guinea pig and he insisted that I wasn't, he'll garantee improvements or my money back, but he did ask me not to go only by dyno numbers but take in consideration my personal feel and track times, all of that sounds fair, dyno numbers can be deceiving some times. I'll have to wait at least until the end of next week.
So when are you going to do it? If we can have your opinion before me doing it it would be great!

Sleestack

Dyno numbers can be deceiving? Not when they are promising you certain gains in hp and torque. There either there or not. I'd say that the potential for being deceived by wishful thinking coupled with rough judgments of "feel" is much greater. Not saying his chip doesn't work.... just don't let them convince you that gains are there if you can't see them on a dyno.

amgme

my opinion would be that "feel" can be deceiving at times rather than dyno numbers. a chip can certainly make shifts shift harder making you think that you have more power, etc. etc. but does not actually improve on hp and tq. i would go for dyno numbers to prove that their stated gain is for real rather than smoke and mirrors.

pocholin

While you are right on your comment, dyno number can be deveiving at time, how do you kno the dyno is properly calibrated from day 1 to day 3? Your car's running temp, and the ambient temp. That's how it can be deceiving, but IMO track numbers and dyno number should be the combination for measuring these king of smaller improvements, although track numbers can also be altered by running conditions (such as temp and humidity)

I really doubt I'll see 24 hp improvements, I'll be happy if I get 15 hp, I'll be extremelly happy if I do see 24 hp, which would mean I could brake in to the high 12s in the 1/4 mile with either increase. The only way to find out is trying it, worst case scenario I get my money back and forget about the deal.


CLK69, why did you delete your posts?

pocholin

It is my understanding that any transmission changes (shift points and firmness) can't be done at the ECU, but have to be done at another device. Can somebody confirm this?

I think I will take the dive with you, I just want to clarify the Money Back Scenario - If They Stand by Their Product and a Full Refund Is Truly Optional, Then What is there to loose? What is the turn over time on the refund? - Apparently This Company sells allot of the chips to the BMW M5 guys, And they rave about it (as per their forum) I plan on contacting them tomorrow. I will post the outcome of the conversation. If I am satisfied with the outcome I will start the process and advise all.

CLK 69

WOW.

Wayne just called me back and told me that I couldn't get the chip tomorrow because their lawers advised him not to because the chip is currently not CARB certified in California. They should be receiving the certification in 30 days though.

Then he said something because of my posts on this board.

"You are the one with the blue car, right?"

What posts is he talking about???

Also he appeard very concernd about before and after dynos..

I wish, I wish, I wish I had recorded those conversations....

Gosh, I wish all companies were as forthcoming as KLEEMANN

pocholin

Ohh yes, I remember reading somewhere that is was legal in 49 states! You are out of luck. I did sense that they don't want to be tied to dyno numbers, yet their hp gains look great, I compared the performance gains they claim for a M5 and it is only 9 HP, so it makes me think that they wouldn't post unreal numbers.

Or course 24 hp gain is under perfect conditions (like car manufacturers), 10% humidity, 50°F weather, cold engine, clean injectors, clean air filters, 93 octane from a good gas station, etc. Like I said before I'll be happy with 15 real hp gain, althouh 24 would be great.

any noticible increase in horsepower read...

....this:

Mach430

It can be done, we've seen it on BMW's many times. But I have yet to see anything positive come from MB software. Hopefully Powerchip will have the solution, but without a dyno guarantee, I would not recommend trying anything.

pocholin

Well, it worked on my 96 impala SS which BTW uses OBDII (as the Benzes), the over the counter Power Programmer Plus. It also works on my Suburban, you get noticable gains and better gas milage. They are advertised as 15 hp or so for what I remember. i'm going to give them the benefit of the doubt and try it, it might be worth for the extra rpm range and the speed delimiter.

Improviz

Ymmv, but the article in question makes some pretty valid points, and I'm staying stock.

Plus, 160 or so is plenty fast enough for me!

Mach430

Not to jump in and promote our own products, but please explain why you would rather do an ECU upgrade for $990 that MAY provide 15hp by changing the way the engine works, instead of our underdrive pulleys that will add 13hp at the wheels (equivalent to ~16.5 crank hp) for $499 (plus 1-3 hours install) and does not in any way affect the engine? Our pulleys do not add power at the engine, they free up power from the over-powered accessories, which allows more to be delivered at the wheels. Our pulleys can also be swapped back to stock at any time, which is much easier than resodering a new chip in your ECU (which is definitely noticable).

Makes Sense, Where can I have this done ? I live in Northern N.J I would be interested in doing this.
