How much HP from headers and dyno tune?

[Saywhen]

You need e85 and a good tune...American muscle added an intake,headers, and cat back (catback not needed IMO) and a tune on a 2018 and got 509rwhp and 461 torque to the tires on e85. That’s impressive coming from a 17 I sunk over 10k in to get 507 out of.

NW side of Chicago, by O'Hare.

Plenty of E85 in your area...

You should have some decent numbers i'd think. I just made 455 on 93 with a tune and jlt intake. We are going to install headers next week and tune for 93, then flex fuel. Im hoping for 480 range.

Should be easy with quality e. My last dyno session was 516/454 and that was in April here in Phx so not exactly cool out. But I stuck with the stock intake to help keep iats down especially in the summers here. Open element just way too high here.

we are gonna clear some holes out in the grill for better air flow, we sealed stuff off real good. I fully believe IATS are only half the story. We graphed air flow stock vs air flow JLT.. I think Im going to post it soon. If they didnt work it wouldnt have picked up over 20hp when going from stock to JLT.

What did you do to get 507 whp out of a 17 GT ? I though the max is like 470-480 HP N/A ?
