The 1-2v shift is rarley smooth as it should be regardless of throttle level. The serious shudder issues are always under light-moderate throttle and never at WOT. Honestly I am afraid it will cause an issue so I have not been at WOT for the last few days. It did it again where it shuddered REAL hard from 1-2 at light-moderate throttle coming through a rolling stop at a stop sign. My 10 year old looked over and asked "dad, what the heck was that?":disbelief:

Flashed back to stock and loaded up my VMP tune. Hopefully I can get answer from Bill. Til then the PHP tune will have to sit on the shelf. I dont have 15k on my truck yet and do not want to shorten the tranny lifespan.:(

Hey SiCityFX4 I have a 07 F150 4.6 with an AFE CAI and my truck does the same backfiring thing when it is cold in the morning. I was told that it was from being too lean and that Bill would be able to fix it with my custom tune that he is making for me, but now I am nervous. I am staring to think that it is from the AFE brand CAI bc the only people on this site that are having the same problems as we are have an AFE CAI. :confused:

AND, if you don't get this behavior at all with Justin's tune, then it DOES point to something that needs adjusting in Bill's tune, doesn't it? I'm sure he can fix it, once he knows it has to be fixed.

I have posted a thread before on these numbers. But I thought Bill might answer it. So I still remain with ?'s of what the values mean.

It has always hesitated if I put any kind of throttle when I first start it up with the VMP/PHP tunes. It has only backfired with PHP's. Just needs some tweakin :2thumbs:.....email tuning is an impossibly hard thing to do.

Sure will...I will try and give em a call and see what we can dig up. Keep ya posted.

P.S.

PHP Rocks:cool_beans:

PHP Out of Office...
 

Well, I just called the shop and the VM says they are out of the office for medical emegency.:yikes2:

BIll/Corey I hope you and the family are all ok:(

Oh crap, I hope so too.

I was beginning to get worried when I didn't see any posts from Corey these past few days, but then Bill showed up today.

Hope Corey's all right. She has a pretty tough road to travel on.

Wonder if her allergies finally got the best of her?

Hopefully everythings ok with everyone.

Keep in mind that only highest priority (lowest number) TC mode takes precedence.

My guess is that what you're feeling might be related to a timing issue. This may also have something to do with the backfiring issue. Let me know which tunes this is occurring on and I'll make some changes to the timing tables which I think should resolve the problem.

Take care.

That would make a great sticky Bill!

Thanks for posting them.
