Do you have a flare tool?

Do you have a flare tool?

I do, just waiting on the word from Whipple. In an earlier post, they said 2015 and 2016 are ready, but not 2017.

Zero issues with my Whipple. I am averaging 19-21 mpg. If I didn't have to sit in so much traffic I could probably see 22-23 average. For reference, Stock I was getting 26-27 on good trips. Lund tune/steeda CAI I was getting 22-24. The automatic shift points have a lot to do with it. This is all what the gauge says not actual calculations with mileage and fuel.

My average for the month of January. Letting the car idle for 3 to 4 minutes to get CHT above 130 before driving and shifting between 2 and 3k rpm.

Looks like I got issues.

Its really hard to say you have issues from your fuel mileage. A lot of that depends on how you drive. My auto never gets above 2000 RPMs unless I'm going over 55MPH or Im racing someone. That's just how gently I press the accelerator and how the shift points are tuned. To replicate it in a manual you would need a light foot and quick shifts. I also take advantage of DFSO by letting the car roll in gear with no pedal input, above 1200RPMs, as much as I can. Stock it was 1700 RPMs so whipple actually made it easier. Many manual drivers today do not downshift to slow down and actually put it in neutral an coast to a stop as its easier. That alone can make a big difference in fuel mileage.

That’s only funny because the gas light is on.

Well I just made a 200 mike trip. The new tune feels better but oddly my ltft is still 5% higher on bank 1 than bank 2 and that would be +22 bank 1 and +18 bank 2. The tune feels much better but another odd thing it did is about 150 miles into the trip is started acting like I had 20% on all gears it would ot huild more than 3-4 lb of boost. I atopped and shitdowncrhe car restarts and did the same thing. All I could do to get it back was reflash with the old tune and then put the new tune back on. After that it kept giving me steering errrs and drive mode:steering feel were locked out. Restarting gbthexsr againa took care of that but then my external ambient temp sensor was stuck at 50 on a day when it was 80. It started working on its own 30 minutes later. Excuse typos. Fat fingers and small phone . I think, after me smoke testing it twice and a shop doing it once with no leaks, either the injectors are not matched or they have issues.

Oh and I got 18mpg on the trip with several 4th to redline pulls. I was getting 10-13 on the old tune. I noticed my voltage is no longer at 14.5-14.7 all the time so I bet part is their controlling of voltage changed.

My LT trims are mismatched by about 4-5% as well. They were with the old tune and they still are with the new. This doesn't bother me much since they even out under boost. 72 lb injectors are probably not all that easy to manage at low duty cycles so, for me, it doesn't bother me. Then again, if it the cause of my remaining driveability issues, then I would.

Note I said "issues" rather than "problems." Old tune car was just plain annoying to drive. It's a good sight better with the new tune...

+18 and +22!!! Ouch. Have you checked your fuel pressure with a gauge? Mine are mostly negative with the new tune.
