Selling my 900+whp 2017 Mustang GT (base) in Oxford White with 12,600 miles. This car can easily drive hours to the track with the AC on, run a 9-sec pass, and drive right home. It dyno’d 903whp/830wtq @ 15psi before the bumper exits and valvesprings were installed, so it should make a bit more...
Hmm my speedo reads low by about 5-6 mph right now because of the monster tall tires.
Does that mean after I change the rear gear ratio, it will still read the same 5-6 mph low?
If so, is there a way a Ford computer could recalibrate it?
I currently have 3.15 gears in my car with 315/50/17 tires (29.4" tall!). I believe swapping to these tires from the 305/45/17 tires I used to use caused my gearing to be too tall, slowing the car down.
I think switching to a 3.31 pumpkin would be the best move to make rather than going back to...
I meant unlimited revisions during the tuning process. They'll revise the tune until its dialed in, which is exactly what any local tuner will do (with less experience than Lund guaranteed).
You're misinformed if you think a Lund tune is "cookie cutter", unless you're lazy and don't go through...
Nice numbers. My tuner said I was having valve float issues as well beyond 12 psi. I did bumper exits, 4 to 1 headers, and valvesprings...I think we're good to go now. But I have the 55mm turbos and GT350 intake manifold.
I was asking because boost levels may vary between street and dyno due to load differences, but that isn't a factor here.
5.2 60-130 on the street on 13-14 psi is pretty good. Probably has a high 4 in it.
Yes, I believe your boost pressure will go down, horsepower will go up.
Is Lund okay tuning your car on that pulley on 93? Their answer is the only one that matters. I believe it'll be just fine, though. I was around that boost level on my D1SC with the 4.88 pulley.
What intake manifold do you guys think is best for my setup (excluding billet)?
Hellion top mount 5562 BB turbos @ 12-15 psi
Stock bottom end w/ OPG
PAC 1234x valvesprings
ARP head studs
GT350 intake manifold (unported)
Those mods seem to...
