Advice needed on throttle sticking/rev hang

[Aldo0280]

Ya i guess its time to try another tuner which i was trying to avoid paying another $300-$400 or more on another tune but i should have just done that since i spent more than that buying throttle bodys & the vmp adapter. But the car ran perfect when i first got it. With the gt350 tb, im, pmas & straight e85 so i know thats not the problem the only thing that changed is the tune. But i had to get a diff tune for smog reasons & i lost the original tune that was on it. Anyways thanks for the help guys ill let ya know if i ever figure it out

Call all the usual suspects and ask if they have your vin on file.

Well idk what 5 star did but they sent another tune today & finally nailed it! It feels better in every way & im pretty sure its quite a bit faster compared to the e85 tune i was just running that had the rev hang issues even though its only a 91 oct tune feels like a diff car! Man what a pain but they stuck in there & finally got it right!

This is why I sometimes recommend them. They don't give up.

Glad you are happy.

Glad to hear!!

Sounds like they have people who don't understand the difference between mustang and f150. Or they do an inconsistent job of paying attention to details.

Ya its kinda crazy how much better it runs feels like it has another 20-30hp & is way smoother & i think it even sounds better! Idk could all just be in my head but i definitely like it alot better hopefully the e85 & flex tunes they send will be just as smooth with maybe just a bit more power. Ill try to find out what they changed & let u guys know. Anyways thanks again for all the help you guys are awesome!

Hey guys my a/c compressor is turning on but no cold air out the vents? The temp actuator seems to be working because when i turn it to hot it gets hot? I had an issue a few months back where it did a similar thing & the a/c actually started working right when i hooked up my gauges but i added about a half can of r134 anyway & it worked fine ever since. I do have a small leak at the high side i think service port (the one on passenger side back towards the firewall) & the r134 could be low again but what doesnt make sense to me is the compressor is kicking on but no cold air? Every other a/c ive messed with the compressor wont turn on when the refrigerant is low? Are these diff somehow?

Actually its the low side service port thats leaking. Must be leaking more than i thought because my gauges show its super low on refrigerant. But what still doesn't make sense is that the compressor still kicks on? Do u guys know if i can replace just that low side service port or do i have to replace the whole line? I tried checking online last time & couldn't really find an answer
