Now how would you fair under that kind of scrutiny at everyone's fingertips???

I've followed his threads before he even bought the CMR software. His tuning knowledge & attention to individual needs is excellent. Am I a "Fan Boy", sure, just as anyone else who has followed his threads over the years. He knows what he's doing, but please don't take my word for it, read it for yourself, It's literally a ~10 year resume online, Google is your friend.

By the way, my C7 went on the dyno with your tune in it. It was the first pull, no heat soak or any other excuse you can come up with. I still love ya, man….

My problem is that diablo says the tune is worth 30WHP, but we as a forum lack real before and after dyno runs.

Heres the thing. My local shop (livernois motorsport) with a custom tuned C7 were able to make 30WHP over stock. I trust them, and therefore i know its possible to get this gains.

for now i will want and see.

30 is a very high number on tune alone...

When you decided not to help me tuning for E85, saying you never used it and never will use it, I had no alternative but to go with someone else. This time around I chose to tune on a dyno instead email tuning. To make a long story short we first did dynos on the OEM tune from the factory vs the last tune you did for me. The results were your tune was 413.66hp/411.25tq and the stock tune was 417.37hp/418.40tq. Then the tuner retuned with his changes and got 424.26hp/424.96tq. I guess all email tunes are not equal.

I’m not trying to “dis” you, I just wanted to tell my story and what I have found out about email tuning for the forum. I too (using the seat of the pants test) thought I was getting somewhere. You don’t really know what you have until you put it on a dyno. There was a significant difference between your tune and theirs (seat of the pants and otherwise). I guess this your first "C7-specific users report...".

By the way, I picked up another 23hp/20tq with E85 (actually E65 for the test) and an E85 tune.

His tune could have made 10 less rwtq and rwhp and still have been 2-3 tenths faster in the 1/4 mile easily. You never said if there was knock on the high end of the pull.

Most importantly, you never said what the power looked like throughout the whole curve??

Unless your trying to make your car into a dynoqueen then we need more info about the whole pull, not just the peak...

This is Diablew vs PowerFab

If you think this is an assassination on Lew’s reputation you need to pull your head out of your ***. Yeah, I’m going to take the time to doctor up a document just so I can dump on a guy who I like and respect. Maybe in time (I’m sure) he would have fixed it, but I wanted E85 and Lew didn’t want to do it so I had to go another way.

When Lew was lying in a bed in the hospital very ill I made a donation to him to help with his huge bill. Ask him, he’ll tell you. Now, what sinister thing can you make out of that?

Usually dynos record the runs in order and you mentioned you pulled lew's first so i asked, that's all.

I'm just looking for facts, not trying to make anybody out to be bad or good. You sound awfully defensive for a guy "just telling it like it is".

I have seen so many people love their car and how it runs until some dyno spits out some number that makes them think the car or tune is not working right...its quite the phenomenon

But if you can tell the car is more responsive and puts a smile on your face bigger than it did previously, then the tune has done exactly what it was supposed to do!!

Its about SOOOO much more than meaningless dyno numbers, dynos dont measure TM, dont measure shift feel, dont measure throttle response or traction, they tell you such a minimal part of the whole story. Have I mentioned I hate dynos?

Thanks

Everyone agrees that the Diablo canned and diablew tune put a smile on your face.

I want my car to be faster, not feel faster.
