I bought a SCT X3[nib] from a well known tuner with 3 custom tunes. I like a firm up shift so in order to get it, I bumped the shift pressure to +25%[on the tuners advice]. I do not feel a difference and I have done it on all 3 tunes.:mad:

This is on my 98 Expedition with the 4.6. I am running 35,s. On my old 99 I had a S/C 1715 and had the shift points maxed out. Very noticeable and I loved it. I was running 33,s on it but it had the 5.4.
Would the 5.4 and smaller tires make that much of a difference in the feel? Its just not what I expected. This is only a preference but I am regretting spending my money on it if I have no other options

Can I raise it more? Another tune or would I have to send it off?

Line pressure is a cheap and easy way to firm up the shifts, but I would be careful with going too far with it. Increased pressure will actually wear the clutch discs prematurely, whereas a valve body will actually help prolong them. I am surprised you can't tell the difference. How many miles do you have on the current (original?) tranny? Could be the discs are already slipping a bit and the increased pressure is not crisping the shifts up because of that. Dunno, but it's a possibility.

Where can I find more info on this? I,m not looking to chirp 2nd gear or anything drastic, just more than what it is now. I know its hard to explain, but I want more than what it is[if anything] now but not too much.

I have 119k on it and everything is original. Though I cannot guarantee, I would venture to say the trans is fine. I had a S/C on this one @ around 105k miles and it did what I want now. Thank you for the reply

Sct x3

I need to speak with an actual owner or call another tuner I guess???

When loading the tune, I click on adjust settings. I believe the first option is global spark, which I do not mess with. Going through, I click on the pressure and take it to 25%. I do that for each 1-2 2-3 3-4 hitting done after each. When I am actually done, I want to exit out. But it keeps taking me back to the adjust options. So I will hit cancel after going through the steps of adjusting the shift pressure. The actual tune installs, so am I not doing something right with the adjustments?

After I back out[cancel the adjustments], the tune will load. But there is no other option after I do the adjustments to save them. So its done, then goes right back to global spark after completed. I have to hit cancel to get out of that screen, then it prompts to load the tune. I have reviewed the CD that came with it, and no luck there trying to figure it out.
I guess my only option is to call another tuner or SCT to figure it out???

I would call your tuner to see if you have the option to adjust the line pressure. Sometimes with custom tunes on hand held programmers, the end user is locked out from any further adjustments.

That is pretty much the only issue. I have called and emailed numerous times. Provided my phone numbers and I have been told I would get a return call.

I am going to call SCT or another tuner. I am just hoping I can get in touch with someone that has one
