You will probably have the fastest Mach in all of Skunk Hollow!Spoke to Livernois this morning. They will be able to reconfigure my module from the ST to the new Mach 1. They are guessing a tune will be a reality within a few weeks of the cars release once they can get hands on a pcm. I'm in.
Bullitt with JUST a good e85 tune can see 495-505whp, they pick up about ~20WHP from a good 93oct tune with about identical TQ gain. Unless the mach1 has a more agressive version of the OEM Bullitt tune, I'd expect near identical number from them.
So considering Ford has to account for 91, and variations in in altitude, it would reason that motor is basically tuned up from Ford. Sure if you change to E85 or a strict 93 only diet there is some power to be had, but absent that it is likely not worth the squeeze outside of drive-ability gains.
You would have to specifically ask a tuner what numbers they are seeing on 91, there isn't usually a huge difference between 91 and 93 tunes. I wouldt be amazed if people are still getting ~15 more on 91.There likely is power left for 91as tuners don't have to care as much about strict emissions or engine durability.
Well thats true for any NA car. You get more gains by tuning AFTER adding parts.
There's ZERO difference if your using a reputable tuner in terms of a tune. For example, LUND piggybacks off of FORD'S Adaptive Octane Logic and usually only puts a cap on timing. However horsepower wise, going from 91 to 94 octane yielded myself something like a 25 rwhp difference. I'd call that significant.
Depends, some manufactures tunes are so conservative we've seen huge HP gains with just a tune, others not so much.
You must have some low quality 91 in your area. I'm familiar with how Lund tunes, he's 2 town over from me and has done every one of my cars :-) On my 2003 Mach1 the difference between 91 and 93 was just an additional 2.5* timing, about 7whp. You shouldn't be seeing 25hp between a 91 and 93oct tune by the same person on a stock car. Unless its CRAZY hot out during one tune and cold during the other and there is no SAE correction used on the dyno. To me that screams the 91oct tune wasn't properly done, or was done with a crap quality 91. Or these are two totally different dyno machines with different calibration.
Which is about right for a 18+, I shoulda been more clear, in my case I'm talking 15-17. As for timing, 3-3.5 degrees more going from SHELL 91 to HUSKY 94. Both fuels are pretty sweet.
And that’s because the bullitt was underrated big time.
since when does Ford publish wheel figures? That 430 is engine.
