****Changed Tune - Results also changed!!!!!****
As many of you know I've grown frustrated over the past few months regarding
my vehicle and it's performance or lack thereof. Most people would be satisfied
with the times I was running but considering the extent of my modifications I felt
that my vehicle should be faster.
I did not start this thread to bad mouth anyone's tune or product. I've always been
they type of person that shared information and data about my vehicle to help others
make an educated decision. We're here to learn from each other and hopefully I can
provide some more valuable information.
Prior to my tune change my car was consistently in the 11.5 to 11.6 range with a MPH
roughly from 120 to 123 depending on the conditions. These are very good times to
say the least.
Prior to yesterday's May 12th Atco track rental my personal best time was:
11.504 @ 122.10 on 12/04/10 @ Atco Raceway(DA: -1300) previous best
I added a CF Hood, 18" Forgestar's and changed my DR's to Nitto during the winter and
returned back to Atco on April 21st of this year. These were the following results:
11.583 @ 122.06 (DA: -249)
11.509 @ 121.88 (DA: -871)
11.539 @ 122.05 (DA: -991)
11.525 @ 121.20 (DA: -1138)
In addition to my winter modifications above I added a CF trunk and switched tunes to
MHP. I made about 25 to 30 passes yesterday at Atco in positive DA. After a few runs on
Shell 93 I added a few gallons of MS109. Instead of posting all my runs I will post a
handful of times to compare.
(Shell 93)
11.573 @ 122.33 (DA: 362)
11.542 @ 121.81 (DA: 362)
11.576 @ 121.47 (DA: 362)
11.633 @ 121.11 (DA: 490)
11.682 @ 120.64 (DA: 490)

11.494 @ 122.96 (DA: 727)
11.500 @ 123.10 (DA: 727)
11.561 @ 123.10 (DA: 727)
11.661 @ 122.53 (DA: 806)
11.656 @ 122.40 (DA: 806)
11.476 @ 122.95 (DA: 1013)
11.484 @ 123.10 (DA: 1013)
11.415 @ 123.24 (DA: 1170) Personal Best - Last run of the day.
Clearly, with my set-up the MHP tune is superior. All of yesterdays runs were in positive DA
and I still managed a personal best. The car was actually running stronger the worse the DA.
I should have listened to Mike(dodger63) when he told me to put in the Braille battery, I may
have run an 11.3. Mike installed it after my best run but sadly they already closed the lanes.
Frustration was setting in and I just went with the tune with proven track results. Again,
I'm not knocking anyone here, just providing feedback for others. I'm just looking to maximize
my set-up and I feel I took a step in the right direction.
Thanks to Andy(MHP) for the awesome tune.
Note: All DA numbers are as per Dragtimes.com
Note: I've used MS109 on my previous tune with no gains to record.

No question the MHP tune is stronger than the Eurocharge tune. You proved that.
I was very happy to see you finally get the results you have been looking for. Im glad I was there when it happened. I cant wait until the fall because your numbers are really going to be great in Neg DA.

An additional 2mph trap speed in DA that was 2000 worse is incredible, regardless of the minor weight reductions! I think you will be very happy when the climate goes back in our favor.

Sorry, but from what I am reading I don't see any real improvements based on the tune change???? You also lightened the car,the rims, upgraded fuel and added drag radials. If there was a change from the tune is was very minor if any. Congrats on the faster times.

The car was taken to the track with my old tune after the hood and wheels
were on the car. I always run DR's, I used M/T's with my old tune last year and
decided on Nitto DR's for this season. The only thing I changed between
track outings this year was a CF trunk(14 lbs) and the tune.
This was in my original post.

my old tune.
Thanks for the congrats.

The trunk saves about 20 pounds, hardly anything on the track. He beat his best time in +1000 DA. If he was running in neg DA like his other runs his results would have been MUCH more apparent.
His previous best with the Eurocharge tune was done in -1200 DA and corrected to 11.66
His best time with the MHP tune yesterday was in +1000 DA and corrects to 11.276@124

I'm not trying to bash anyone here just posting my experiences. In my
set-up the MHP tune is superior.

Nice write up Petro.... I hope people don't take this post as negative in anyway towards anyone or as an opportunity to start a pissing contest because this is NOT what this post is about. This post is about raw data collected from the track. Petro has always shared his results with us whether good or bad and have always provided extreme details on all his mods and runs in the benefit of the community. So please don't pollute this thread.
From the data given, it seems that with the MHP tune and new trunk, Petro ran 0.1 seconds quicker and 1 mph faster in DA that was 2400 ft worse than he did with his previous setup with the Eurocharged tune.
Nice writeup Petro, we really appreciate it

I can say that paddle shift speed was significantly increased after the
tune switch. I remember one time at the track in manual mode with my
old tune I hit the paddle to upshift and nothing, hello rev limiter. Now
it's instantaneous.

Those that truly know me, know I'm upfront and honest about my info
and data. This is not a thread created to bash another tuner. If you read
the first post, you would see I didn't even mention the tuners name.

Big time congrats! There is no doubt Andy has a stout tune. With N/A cars being very sensitive to DA, that is one fast time. When the DA kicks back into the negative, that time will only get better. I would even go out on a limb and say better by alot. In my old C55 I picked up 2 tenths in the 1/4 mile with a 1500ft DA swing with a bad trans. What you will run when the weather is right is anyones guess.. But its safe to say you ARE and WILL BE faster than an 11.41
Awesome right up, awesome results. The feeling must have been great.
Best Regards
Mike

Yes I saw the DA. I also see your times improving as the DA (air temp) increased. It appears that the theory that you would run faster with a lower DA is not supported by the facts. Could it be the tune is a little too rich and this rich condition improved as the DA climbed.
Not trying to start an arguement-- just trying to understand the #s and maybe help.

While I don't disagree that the MHP tune helped your times, I do think the impact was marginal. Based on Propain's corrected times, you ran about .4 sec faster than your previous best. I think it's reasonable to assume the trunk, lightweight rims, and nittos are responsible for at least half that improvement, leaving the tune to contribute the other 0.1-0.2 improvement.

It's possible, I haven't had the tune long enough to really be sure.
I have maybe 300 to 400 miles on the new tune.
Many of those runs I listed were hot laps, 4 or 5 runs in a row.
I left my slips at work but I'm pretty sure my last run was the tail
end of a 3 or 4 hot lap. I'd have to double check to be sure.

Just to clarify.
The only thing I changed between my last two track events was the
tune and the trunk.
On April 21st, I ran my old tune, Forgestar's, my hood on Nitto DR's.
On May 12th, I ran the new tune, Forgestar's, my hood, trunk, on
Nitto' DR's.
The only difference was the tune, trunk and the DA.
