Looking for Tuner
I have a 02 GT. I am looking for a hand held tunner that will change my shift points. This may be a little hard to explain. My computer automatically shifts at 5800 rpm at WOT from the dig. I am running a built engine dyno tuned at 456 RWHP at 6500 RPM. When my tranny shifts at 5800 rpm, my hp at that point is only 397. Most of my power comes up top. I would like the tranny to shift at 6500 rpm rather than at 5800. My rev limiter is set at 6600.
From what I understand, hand held units changes shift points from rolling rpms -- to set up different passing gear shift points. I don't want to change that. I just want my tranny to shift in all gears went at WOT at 6500 rpm so I can benifit from the entire rpm band.
Does any of this make sense to anyone?
Please advise.

before you go looking into a tuner, does your tranny have a shift kit and tranny cooler already installed? i know that some of the tuners run into problems when a shift kit is also installed.

I will have to think of something else to raise my final shift sequence to 6400 rpm.
Thanks

also with a built boosted motor, you may want to go upwards of 6800 rpms to take advantage of the superior rotating assembly and to maximize performance during the shifts ie being able to shift and stay in boost

I replaced my tank with a 03 cobra tank and dual pumps. But dyno still indicated I need more fuel. I found out the cobra pumps put out only 115 lpm for a total of only 230 lpm -- less than the 255 lpm a single SVT Focus pump I was running.
So, with that, I took out the cobra pumps and snapped in 2 SVT pumps in its place using the cobra plate that came with the pump assembly. Now I was running 510 lpm. Yet dyno said it wanted more fuel.
I changed the 5/8 diameter fuel line to 7/8 line all the way to the rails and that did the trick. Dyno jumped from 409 to 456.
Now I need 60 lb injectors to go further. Also MAF has to be recalibrated.
The new Cobra tank, dual pumps, SVT focus Pump and fuel line with fittings cost $1334. I can't get a discount at my father's store because it is dealership products. Now I have to sink another $600 for the injectors and maf to advance another 3000 rpm to get to that magic curve you mention.
Thank you very much for your input. I learn something new every day.

hmm, if that is the case, your tuner probably set your shift points as such to keep you from running lean. your tuner should set your shift points while adjusting the ecu

Believe me the shop I go to is inept. This is why I am asking you guys these questions. I almost lost my tranny because of their laziness. When they took down my old 4.6 to replace it with my new DSS long block, they took down both the tranny and engine together and laid them on the bare garage floor with nothing under them. This crushed the tranny oil pan enough to cause oil starvation in the tranny to the point when I hit on the thottle, the tranny valve body would loose enough pressure and slip into neutral.
That is just one example of several mishaps that cost me big time.
Anyway, back to the tune and shift points. Since my engine is making power all the way to 6600 rpm with out any fuel issues -- enough pump and injectors -- I feel it can handle a stout 6500 final shift point so I can benifit from the upper power band. There is a big difference in HP.
As of now, the only way I can get into the 6500 area is to run all out on the highway at top end. I did that and used up all the speedometer at 150 and was at 6050 rpm.
I don't want it way up there. BOTTOM LINE: I want my Mustang at WOT to shift at 6500 in EVERY GEAR and get the entire 456 hp it makes. It will be a major difference from shifting at 5800 making amost 70 more HP.
Is this logical?

I don't know. The shift point was always set at 5800, even when the rev limiter was set low at 6000 -- when I was running 363 RWHP non intercooled and with the cheap stock plastic pistons.

So why not find a new shop? Do you live out in East Bu-Foo and they are the only game in town?
