Question for guys who actually have the the Roush Kit

[Greyhorse]

That's a helluva 60' to run 11.30

The 11.30 was actually i think a 1.71 60’ didnt do a long enuff burnout but was scorching hot that day so i knew i wasnt gonna get any good runs

Like i said.

Thats what i thought i would run in the 1/4’ but like i say hung up at 121 for both runs nice timeslip in good weather a10 auto and a good tire i think that is a good representation of the phaseII (i assume you are phase II!??)

Yes on Phase 2. Toyo Proxes R888Rs 26lbs. 5 gallons Sunoco 260 GT on top of an 1/8 tank of 93. 56 degrees 68% humidity -601 DA

I have the phase 2 upgrade and my IAT2 temps run around 40 over IAT

Make sure you dont have air trapped when i got mine back it was abt the same delta over ambient i was like damn man temps didnt even improve couple days later popped the hood and my tank was low had to add some now while cruising abt 32 degree delta

I will never have an issue with high IAT2s. Installed a Killer Chiller a few months ago. Drove the car last night, first time in over 6 weeks. Doesn't matter what the temperature is IAT2s match ambient.

It is now the general consensus that it will shift to 7th at WOT in normal mode? I tried it this morning and mine shifted. I didn't want to try other modes because traffic was picking up and my "Mexico" is more like Southern California.

I ran from a dig in Normal mode and all of the shifts were pretty decent....MUCH better than the original P2 cal and better than just after flashing the current cal. Car pulled hard and felt better than I expected in Normal mode. It is raceable in that mode....not as good as Sport or Drag...but not bad. I will probably give it a try.

Good to hear your car is working out.

This is crazy! Time slips above are over 1/10th quicker in the 8th and then falling on its face / being held up on the back half. This 10.7 run had a 7.0 8th with a nice 27mph back half. The 6.9 slip only had a ~16mph back half if hitting the wall at 121. Rightfully any supercharged S550 should have a 25mph back half. I feel your frustrations!! I’m rooting for your Greyhorse!

If it were me, PBD would be who I would let tune a Roush, I actually find it amusing VMP built Stangmodes car but he had PBD tune it. I would’ve thought VMP would’ve said no, it’s our package so u get our tune?

Anxious for the Equator to leave the area and cooler weather to get here. Time slip posted was 3 months before Killer Chiller was installed. It's gonna help,question is how much?

Did you install the killer chiller yourself? If not, what did the install cost?

I would like to see before & after dyno sheets and 1/4 mile times of a P2 Roush and the same car with a custom tune, no other mods and 93 octane fuel. If Roush can fix the 6-7 shift and not screw up something else, I would be pretty satisfied with their tune.

As far as I know, all the online videos that make comparisons start with an early P1 tune. There is a lot of headroom with that tune.
