Interested in more information on this. Is it Plug and Play? Price?
It's off a Mustang, but they're pretty universal, definitely not plug n play. I took it on trade a while back, but doubt I'll ever reach the point where I need it.

yea i use the VP Octane Booster and Torco Accelerator Octane booster pretty regularly and i have the Auto Octane tune from Gearhead. My question for the Auto Octane tune is does it just keep going up octane til it starts knocking again?!?!

You'd have to ask @mattr66 for specifics on how he has the tune set up, but I'm sure there is a knock threshold that it won't add over regardless of the octane.

I will leave this here.

If you plan on running E30, there really isnt a need to upgrade the intercooler. Yep I said it.

And for that matter, for most there's no need to upgrade the HPFP for E30 either.

with a good tuner and not freezing climate I agree.

yep, Oklahoma I never had an issue until we got below about 40* then it was time to switch back to 91. With Arizona you don't have that issue though haha.

I had to have Brad pull the stock HPFP e30 tune back because it was getting into the high 20's and low 30's. I was getting uncomfortable with the cold weather dip. Zero issue now with the FS HPFP.

Subscribing. '14 SHO with 137k miles. I'm replacing the fuel filter and pump with a Dw300c. I have E85 in my area and HAVE run the E30 mix. I wonder if the SHO made more power?
