Steet tune question

[BigRobRN]

This may be something I need to ask Eric, but I'll give it a shot on here.
I installed the street tune for the first time yesterday, and again I was shocked at the increased power over the tow tune.

I couldn't keep the tires stuck to the pavement at all, and it sped through the gears so quickly that it seemed to hesitate at the end of each gear with a slight hesistation. This could very well be normal. I don't know if it would have ever stopped spinning had I not let off the gas. I must have left a wide black streak 1/8 mile long.

I just want to make sure that the hesitation at the end of each gear before it shifts isn't a tranny problem, or if its just the pure power increase that sends it to the shift point that much quicker.

I haven't noticed any hesitation when going about 30 and then letting the hammer down, other than the turbo needing a second or so to spool up and let loose.

Any ideas, other people noticing hesitations?

Hello, anyone?

Could this be a fuel pressure issue?
Turbo issue?
I've noticed I'm only building up maybe 22-25 lbs boost per stock truck gauge.

I think it shifts just past the peak power RPM, so maybe you're feeling it flatten out a bit before the shift.
After you get some studs, you'll really love the eXtreme Street tune!!
It's flat-out stupid fast!! The eXtreme doesn't have any flat spots in the power delivery.....except for the ones your head will get from slamming into the seat!!

If you just loaded the file your tranny needs a few drive cycles to "learn" the shift strategy. Whenever I load a new file I make it a point not to just go out and rip on it. The shift flares you're experiencing should go away after a few days of driving it. It's the nature of the beast and will happen everytime you load a new file in to your truck. The tranny will reset and have to re-learn the shifting every time.

and as previously said, if you like the street tune, wait until you try an Xtreme file...

Like shu873 just drive it for about 75-100miles let the tranny adapt to the new power if there is still a problem email Eric he will take care of it

Not to take off topic but it falls along the same thing. I was running the street tune for a little bit then put in the xtreme street tune and it still does the same thing. When I am rolling at any speed then floor it, it will shift down then after a couple seconds it will drop down another gear?? Why wouldnt it just drop down 2 gears to start instead of one at a time? Anyone elses do this??

You need to put in your gear ratio and set the reves for tire sizes. Helped me some but mine does the same thing. They also told me to make sure I am running all ford filters for fuel and oil because their tune demands so much fuel.

I have all ford filters but doesnt eric already set that stuff in his tunes? I gave him my tire size but not my gear ratio. I will give that a try and where would I get the revs for my tire?

[utlonghorns416]

I am running 285s 70 r18 and my tires revs is 615, he will tell you what revs are need for your tire size.

Well currently I'm using Napa Gold fuel and oil filters. Maybe I should switch back to Motorcraft?
