Whipple Installed, Dies with any Tune Besides Stock

[MTF]

What kind of cats? Cheap High flows may present a problem.
And they don't last long in a Supercharged application.
And are you turning off the rear O2s?
Or did you do the rear O2 extenders so you can leave the rear O2s on?

Can you grab the part numbers off of one of the injectors. Even better would be post up a photo of them where we can see the engraving on them. There are several versions of the 60lb injectors out there, if you were running them on your lightning successfully the injector data from the lightning should transfer over directly.

The fact that it runs on the other tune but not this one leads me to believe its tuning rather than mechanical. Has this tuner tuned the roush raptors before? If so they probably have the decryption figured out, the difference in the way the truck runs will boil down to the MAF sensor tube size difference between roush and whipple which would give the exact symptoms you are talking about. MAF scaling is the single most important tuning step on these. Bad injector tables can cause the same symptoms.

I just did the cigar smoke test, and I'm not finding any vacuum leaks.

The boost bypass line was installed by Whipple, and does appear to have a slight kink in it. I'll see if I can address that once I recover from huffing this cheap cigar.

Injector part is 107961 which I shared with the tuner.

My thoughts exactly since it's running on the stock tune.

I'm not sure on the brand of cats, but I have extenders, and the truck passed emissions last summer running a tune from the same tuner.

Ok that's good that your using O2 extenders.
There are a few owners that had the stock cats welded back in and/or switched to the Green cats from Kooks.

Also the Whipple Gen 4 compressor needs just about a new calibration table.
Tune files from the Gen 2 compressor (which is the most common) won't play nice.

I've found another tuner local. One man show and mobile. He does SCT and HPTuners. He's very confident in HPTuners and prefers them. He's tuned Whipple Raptors before, but it's been ~5 years. Bonus, everything is only $500 for a full Dyno tune for either software.

I finally heard back from big name tuner today, and they've given up, but did not offer a refund.

Well, I wish you good luck with what ever you decide to do, keep us updated.

Do you know what your short term and long term fuel trims are? If it's trying to add fuel you have a vacuum leak or un metered air. If fueling is not right it's best to start with a fresh set of O2 sensors bank 1 both sides. That way you know you have accurate readings. Motorcraft or bosch O2 sensors only . No Vatozone specials

Thats not necessarily true. If the tune isn't set up for the MAF housing he's got his fuel trims are going to be jacked up even if the intake is completely sealed. LTFT+STFT is the math used for dialing in a MAF housing.

@Stricken open up a dialogue with that tuner, make sure he has the flow data for your injectors available. They aren't the FRPP 60s so Ford's data may not work for them. If he has tuned whipple raptors before he should have all of the specs necessary for the manifold and MAF changes already.
