I have not put that is on my radar. My car is a 17 with 20k on the odo so I would hope the pump is ok.
Funny thing. Under boost full load the trims are much lower about 7-9 last time I looked
Reflashing doesn’t fix an issue, do you have knock limiting on? Sounds like it is and it limited throttle.
Knock limiting is off only power limits programmed are 15% 1st 10% 2nd. I have the new tune on now and it is acting fine we will see if it happens again on the return trip it was just odd it had been boosting just fine and I went to pass a guy downshifted and felt almost stock at first I thought maybe my belt was slipping but that wasn’t it.
This exact thing happened to me. New tune felt great for the 1st 100 or so miles on a spirited drive. Then all of the sudden power was way down. I started to experience stumble/hesitation on tip in on 5th and 6th gear and boost went way down. With the windows down I can now hear a whistle when it should be getting into boost. Never heard that whistle before. All hoses appear to still be in place. Took it out again today and sure enough it is still running like crap now. Still have the whistle and little boost. And a terrible stumble on tip in, especially in the taller gears. I did do a crank relearn and knock limiting is off. I'm on 92 octane and it was about 45 degrees out both days. 3.75 pulley.
How do we put it back to stock first? Couldn't find an option for that with the latest version of Flare. I flashed the new tune over the old one and it seemed to work ok. Do I need to redo something?
If you downloaded the latest .flare file you will need to open your old .flare file to have the restore option show up right under the program option. The new file will not have your saved stock tune in it if you flash it over your current Whipple tune.
Do you have a 2017?
Thanks, yeah, I just figured this out. For anyone who did what I did, you can reverse it by restoring from the current tune back to the old tune. Then open the old tune and restore again to get back to your stock tune. From there, you will be ready to load the new tune again, and it will have your stock tune saved for the next time you restore.
yes I do a 2017 GT PP. Dustin gave me the tune, keeping his word, first before the release to everyone.
Yes your installer should have copied the .flare file from their laptop to the Whipple thumb drive that comes with the kit, after loading the tune to your car and gave you the flash drive with the .flare file on it.
Have u ever looked at your ltft while your car is idling,warmed up??If they are let's say 25 at idle and then u raise the rpm to 2k and the ltft drop that is a classic case of an air leak somewhere.Also if u don't do a kam reset after fixing a fuel trim issue fuel trims will be the same on the next startup and take some time to relearn.Not sure if flashing over another tune does a kam reset.
At idle Bank one is 4-5% band 2 is 1-2%.
