Whipple Stage 2 with 3.625 first time at the track results

I have a similar setup with the 3.7 pulley, and I make over 721hp on the dyno...

I have shifting issues with the Whipple tune on my car. I picked up 3 tenths and several mph by shifting the car myself. What's you mph in the 1/8? What was the DA on those runs? Do you have a boost gauge to make sure you are at 11psi?

Your problem is you have the MAX rpm set to on! Turn it off.. Whipple is working on a revision current. It does not work on the track or street your shift points will be way off and you will make less power due to it. I have the same setup and the moment i turned the max rpm off the car went 10.7 @ 134.

yes this turn that off. Also do you have the updated tune?

OP it sounds like you and I have an issue that won't be fixed by turning the rpm max off. I've played that game and while it did shift at the correct rpm, the car still could run good times in auto. The 2-3 shift is so slow in mine that the car loses all momentum on the track. Manually shift it and it goes away

Just something I noticed, but you said you are running 3.15 gears, but the Flight control shows 3.30.....

If that is off, could be a major hiccup.

Saw that and though the same. When I click to edit and change it to 3.15 , it reads 3.15 without editing. If I go out of the field it reads 3.31 as in the picture .

I don't know now if it is indeed at 3.15 or 3.31

I think that as far as MPH the sensor at the track was off. I do not know if the ET was correct.

2012 GT500 stock ran 108 MPH (see slips 1 and 3). That should be a 118 miles trap car.
2013 GT500 stock ran 118 - that should be in the 125
2013 Boss 302 stock ran 103 - that should be in the 112
While on the line waiting I hear the commentator mention a 9's ET car ran 128 MPH (that should be close to 140 mph)
Another guy there 2015 auto, catback, flash and intake ran 106 trap that should be in the 112

Something was wrong there...

My car was pulling hard and felt strong through the power band, the power should have been there. The shift points I don't know

Now I question the slips...

I'll go to another dyno and verify power. Also data log shift points while in there with my X4.
After that I will go to the 1/8 near my work place to compare ET and trap and go from there

I haven't tried on my 2015 but in the 2013 the response was so slowww that either I short shifted or hit the rev limiter.

Did you have any issues with the paddle shifter response?

That's cuz y'all use this whipple calibration I'm in the 10's with my whipple

The response is pretty good in mine. It's not a DCT so you do have to learn the timing a bit. I hit the rev limiter on my 1-2 shift at the track because 1st gear goes by in the blink of an eye. It just takes some getting used to. Unless they can fix it, I'll be going custom tune next year.

So I am having similar issues with my Whipple tune, pretty much the exact same mods as OP. First time out at the track the car went 11.01@130, right off the interstate after an hour drive, in 88 degree weather, right as the sun was going down. I had a 1.71 60' and spun some too.

Second time to the track I did not fair as well. Ran an 11.18@127 my first pull, spinning all through first with a 1.83 60'. After that it got much worse. The second pull my 60' was a 1.71 and the car felt good and then once I hit my 2-3 shift the car stopped pulling. Ended up running an 11.4@114. The temps that day were extremely hot. Ambient was like 95 degrees upwards of 80% humidity, DA I believe was around 1500.

My initial thoughts were some heat soak and the car was pulling timing. Also, my last dyno pull after the headers we could see the car was definitely pulling timing. My Guardian settings were MAX RPM and Knock was on. I did some data logging and you could see it was pulling about 2 degrees of timing I believe and the shift took 1.4 seconds. [MENTION=19816]Highvoltage16[/MENTION] can help me out here since he is the one who read my logs. After turning the RPM to normal and the knock limiting off the car felt much, much stronger. Looked like it was advancing 4.95 degrees of timing from WOT until shifting. Shifted in about .4 seconds too. I believe this may be your issue as stated by a few members already, I just thought this story would apply to you. The car felt super sluggish after I put the headers and it is still hot down here in Louisiana, so heat soak is killing me. I plan on heading back to the track on the 6th of November to see if there is a change but just doing the pulls I can tell you the car feels ten times better than it did. I hope this helps.

my buddy has the Whipple 3.725 or whatever and ran 11.5@125. Manual 3.31's soft launch full exhaust

I have 3.15 gears and my flight control also shows 3.30. Wondering if this is happening to everyone with 3.15 gears????

same here. It changes back to 3.30 if I edit it.

Same here. @whipplesc any input on this?
