If you tune the IFR in for L-terms the car will be good if it goes into a limp mode and only runs on the VE/IFR table

here's an update. the truck seems to be running pretty good. ltrims are all negative from 15-80map. 85-105 they are still +4, don't know why. my a/f ratio at wot was anywhere from 12.8 all the way down to 9.8. I adjusted my PE table and ran it again. Same result. weird.
I also noticed that after running wot a few times, my a/f while cruising was no longer 14.7, it was 11.25. it also said my commanded a/f was 11.25. Why is that? Does it just get stuck in pe mode?
I did a few 1/4 mile runs using my G-tech. My reaction time is BAD. I ran 14.7 the first time in 4wd then 14.4 the second time in 4wd. 0-60 was 6.0sec and top speed was 99mph. It felt like it wasn't going anywhere for the first couple seconds. Something feels wrong. I didn't log it unfortunately. Shouldn't I be high 13's or low 14's?
I revved to 2500rpm or so then put it to the floor. I wonder if i should not go all the way to the floor right away. I'll keep messing with it.

The 11.2 AFR is COT.
Temporarily turn the cat over temp off (COT, Lean Cruise tab).
Also, post your current caibration and logged data somewhere.
Internet guessing takes too much time.

Ok, so I'm gonna start over.
I was thinking I'll put the VE back to stock, put the MAF calibration back to stock(modified it for the ported TB), set the PE all to 1, turn off the COT, set the commanded a/f ratio to 13?, do i need to do anything with the open loop and closed loop stuff?
I should reset the fuel trims and drive under 4000rpm and under 60% throttle for 50miles or so. Then start logging. Then adjust my IFR based on ltrims? or should i adjust my VE using the wideband error stuff? This is where i get confused. Do I do both, or just one of these things?
Assuming I'm starting from scratch, can someone tell me where to begin? stock VE, IFR set to stock for 42lb injectors, PE set to 1, etc.

tried disabling that COT thing, nope, still gets stuck at 11.3afr after i stomp on it. This heat is making the truck run like ***.
the good news is my ltrims are right on. my wot afr is right on, seemingly. had to reduce the timing at wot down to 13ish. truck doesn't feel strong at all today. since everything else looks good, i'll blame the heat. ect 210F, trans temp 200F.

Email me a copy of your current calibration and that data you just logged.

Tuning sucks. 
Who ever thought when i purchased the whipple that it would have taken over all of my free time for the last 2 years. holy ****. it has never run right. over $1000 in "custom tune", "dyno tunes", and tuning software. Still runs like ****. Thank you to those who are helping. I would be TOTALLY lost without you. Someday, hopefully soon, i'll be able to do a 1/4 mile run and post up some 13.xx numbers. We'll see.

God i was thinkin abou gettin hptuners and readin this whole post makes me wanna cry. I hope that i have a REAL good mentor when i get it. You will have no issue getting into the 13's when you are done. Maybe into the 12's as you could easily make 550 hp. GL

With that said, find a good tuner on the east coast and travel to them. If it's been 2yrs it will be worth the time and money.

Just need to get him to Matt before he's out of the country.

I'm getting mixed information. Should the ifr table be set to 41.67 accross the board and just tune the VE via ltrims OR should I adjust the IFR to get the ltrims inline? I'm so damn confused. Why did I buy a wideband if it has nothing to do with tuning? So far, nobody has made any mention of using the wideband reading to tune. Is it just for PE stuff? HELP, HELP, HELP!!!
oh, and thanks again for those who have taken the time to look at my tune and help me.

Don't flatline the IFR unless you have a rising rate regulator. It should be a relatively smooth curve if you look at the graph. Yes, the WB is mostly just for WOT - the easy part!

I used the IFRT to get my LTFTs inline (0 ~> -7) before doing anything else. VE the last thing I touched.
Wide band is used during timing/fuel adjustments for part throttle and especially WOT to make sure you're a/f ratio is correct. I'd have it in the 11.7 range(+/- .2).

Is the fuel pressure regulator the same on trucks as it is on cars? I haven't touched mine. My fuel pressure at idle is 58ish. At wot it's high 60's.
Should I be adjusting the IFR or should I be adjusting the VE?
HELP, HELP, HELP!!!!! thanks

stock head and cam. ported throttle body. can't understand why the wideband reads 11.25 on every cell after i do a wot run. totally whacked. clearly it's wrong right? or am i getting stuck in some mode?
I'd love to post up a log, can't figure out how to.

I'd love to post up a log, can't figure out how to. Also can't figure out why my truck falls on it's face off the line. Timing drops to 0. kills my 1/4 mile times. i swear it's the damn TB causing all this crap..
