If I were you I'd forget about making a special trip for tuning with Jerry and keep working with Cory....

Cory will be able to tell you a lot more about what is wrong with your tune (if anything) and can put the EXACT same tune that you liked back on the car. Having a second tuner messing around with the car at this point only confuses the process and makes troubleshooting that much harder.

Besides, if the IC pump ends up being bad... Jerry isn't going to be able to make your car run any better with his tune. You'll be spending money but not getting anywhere.... Confirming the existing tune is a 100% correct Kleemann version will be a huge step in diagnosing and resolving your power loss issue.

Yeah the only thing I'm worried bout is driving to Jersey & it ends up not being the tune.. but after Cory saw the graph he said it seems like a mechanical issue or just a ****ty tune.. Recommend a compression test which I did, which checked out good

What was the compression on all cylinders?

They all read around 100 on the gauge.. I've been told my gauge reads low, but all cylinders were consistent.

That's low man!

I'm pretty sure it was just a cheap gauge.. I asked a few people about the results they all said its fine.

No, that's way off, even on low reading gauges you should have 140psi at least

So your saying every cylinder in my motor has low compression.. Hmmmm I don't think so

Something doesn't make sense, did you do it right?

My buddy did the compression test , I hope he did it right

Something doesn't sound right, 100psi on all cylinders, there's usually 5psi difference between some cylinders which is fine.

How long have you been driving that car with being rich like that?

They all read "around" 100, some were 90's some were between 100-106..

I'm not sure how long it's been like this, first time I had it on a dyno.. was told by Paul it held a steady 10.5 AFR when it left the shop which is obviously false.

Don't do any tunes until you are sure about the compression test, some E55s are for sale these days without compression tests being done before buying

Going to send my ECU to Kleemann.

Some of the cheaper compression gauges glitch out around 100-120PSI. I ran a compression on my Toyota 4.7 and my E55 before purchasing and both sat right at 80-120PSI. A quality gauge read accurate and within spec.

Thus was a cheap harbor freight gauge lol

Do you have cams in that car, wouldn't that lower your compression a little, ?

I do have cams, I'm not sure if it would lower the compression.. Hopefully someone will chime in & let us know.

Here is my kleemann tuning on pump gas

Hopefully Cory confirms my tune is messed up & he can fix it, so I can have graphs like yours lol

I also have carbon fiber renntech air box,180mm pulley,82mm tb and super sprint mid section with ss race resonator on top of your mods lol

Good luck on getting it fixed!

Ill be happy to break 500whp & run 120+ mph! What's your best time at the track ?

11.2@124 going from memory but then went 185mm pulley and blew my tranny.I gave up dragging the car now lol

18k in parts and labor to get her up and running again lol

That's nasty man!! Yeah I just wanna run her once or twice at the track .. But I enjoy Hwy rolls a lot more lol

Do yourself a favor and do some reading before you take too much advice from Skratch77.....

(Start reading at around Post #46)

He's pathological..... Posted up dyno graphs of an SLR motor claiming his E55 was laying down close to 600WHP. Got totally busted by MBWorld and slithered away for almost a year, not daring to show his face in this forum again.

Apparently he's now trying to quietly ease his way back onto this forum.

He has never admitted to lying about his dyno results, despite being caught dead-to-rights. You'll have to decide for yourself if you want to take advice from a guy like that.
