With a little practice and some aid from ESP, a 1/4-mile time improvement of 0.5 seconds and a trap speed increase of 5 mph are not unusual. Those numbers are significant. All this and daily driveability doesn't diminish. Warranty, on the other hand . . .

However you can get significant increase in power that you can feel, not just 20-30HP. My G55 K4 dynoed at 389HP stock and after the mods, it dynoed at 491HP at the whee. This is a increase in wheel HP of 102 or an increase of 140HP to the crank. This takes the HP from 469 to 654 and torque went from 420 to over 700. You should see the 4wheel drive spin all 4 tires at take off. So it is not just an excercise in futility.

Kleeman should have some way to datalog the dyno runs, if they don't, then they are nothing more than backyard hacks.
Minimum would be to fit a boost gauge while dyno tuning to see what boost you are getting if thats OK and the AFR's are ok.
Then hit the track and see if it's not just the dyno reading low.
Could be convertor issues?

Ok have good news and bad news, the bad new is it dyno'e at 417whp, and 477 Tor. The good news is we know why. My CLS was at MB for a fuel pump replacement, while it was there they reflashed the ECU, I called Cory and I sent him the ECU today. He said once it's done I should be at 500whp, which is what expect I should have back by Thursday and I will redyno it. and let everyone know the final outcome. I hope.
So will still awaiting to see if the mods are really worth it!

I don't know . . . . . you might have good news and not so good news - the bad news might still be coming. Unless I'm missing something here, I don't see how they're going to get 83 HP from an EC tune. Did Cory say anything to you about what's causing the large discrepency? If not, it might be worth another phone call. I don't think the cams are aggressive enough to need an ECU re-write. If he can't explain it to your (our) satisfaction, maybe he should personally deliver it to you. Just a thought.

I'm with Grumpy on this one. I really hope that I'm wrong and the car makes a lot more power then your current 417. This would give me a little more hope that I may actually get my problem fixed. Right now the car is going in for a compression tesst tomorrow to check if there is anything wrong with the valves. After that it seems like nobody has any idea what to do next, so I guess we'll just have to wait and see what happens.

I alittle worried too, but I hoping for 480 at the least, so 63 different. Anything under would be very bad, maybe their a hidden limit, or the cams and tb are a waste of money. I know all tuner give bigger number, so I lowered my expecations. Assumming my car base was, let say 400 then 480 wouldn't be horrible and I think realistic. Kleemann claims 171 hp at the crank increase for K4 with exhaust, I don't have their exhaust. So let say 156 without exhaust, so now lets take 20 percent off for a more realistic number, so 126 about at the crank, now 19% off for drivetrain loss, so 100 at the RW. So and 80RWHP increase is realistic. 100 is wishful. But we will see. Cory seemed pretty confident that 490-500 can be achieved. The independant tuner dynoing the car said that with the proper tune, it should reach 480. If I had to bet money I would go against it, which is going to get me mad. I am trying not to think about it, lets see the facts first. As soon as I get more results good or bad I will let you guy know. Thanks

I can relate to what is going on here. Cory emailed me my baseline and it was down from the "factory" claims. The k2 upgrade they added did what they said it would within 5-10hp. My next amg or sports car will be dynoed before I buy. My engine was built by Guido Nordheim and he left out about 35hp and 20lbft but the k2 added 94hp and 110lbft. The only problem I have had with the car is the cel due to the down pipes. I am a little upset about that but its the price you pay. I have sent my ecu to kleemann twice but the ecu will not let us get rid of the cel. They did send me the parts needed to relocate my o2 sensor to fool the ecu, we will see if this helps. Good luck to you and maybe you just have a weaker car as I did.

Well that settles it then....Guido F'In SUCKS!!!!! I have a Guido motor and she pulled 496 on Cory's dyno....WITH ECU mod and K n N's. That means I was pumping wellll below factory specs to start. Again, while Gid-e-up pulled 517 bonnnne stock.
Never thought I would say this but next AMG I get......I am checking the faceplace first. If Guido signed it....walk away. How the hell can these guys make one engine with 40-50 LESS hp with all the same parts in the shop.
DEATH to Guido!!!!welll ya know maybe not death, but I'm still pis sed!!!!!!

Thats BS guys, these engines are tested before they go into the cars, if they don't meet the spec's they give us by 1 to 2% they don't pass inspection. I was just at the factory 3 weeks ago. Also who are you going to believe a Billion dollar company or a small little tuner that can't live up to what he's selling you?

[QUOTE=Ted Baldwin]...........i have the O2 sensor error code and the check engine light. I did the ECU re-call work thinking it will fix the problem and it didn't. I have placed a spacer before the o2 sensor to fool the car and it worked for a week and check engine light came back on. I do not know if this is the same thing you are about to do. Let me know if it works, I am interested in a solution

This cel was one of the things I asked kleemann about before the mods, but like anything if you monkey with one thing it will affect another. I dont know what they sent me in the mail. They could be spacers they are threaded round bolt types with some wire as well. I have not had the time to do anything with it. I know kleemann was working on some new program to try and get rid of the cel so I may just wait it out or live with the light? I was wondering if I added the kleemann cats if it would go away? Just a thought. I will keep you posted of any progress. Thanks for letting me kow your issue too. What year is your car?

Headache
Yo guys, I have a headache just reading this. I can't imagine having to live through this with my car, I wouldn't be pissed I would be livid.
I think the mistake here was not getting the car dynoed before all the mods. It's hard to tell now with out a baseline if the mods worked or didn't.
I don't know much about these mods but there is always a starting point with any modification and since the car was never dynoed I think you'll keep going in circles.
Just my 2 cents. Good luck hopefully you can get some of your money back.
