Default How much HP will the GIAC race fuel mode increase?

how much hp will it increase from the standard pump GIAC? Is it worth it? How much would it cost to add it on to my ECU?

DO I NEED THE RACE FUEL PROGRAM TO USE RACE FUEL OR CAN I JUST USE RACE FUEL WITH THE STANDARD PUMP GIAC PROGRAM?

Default General rule of thumb is 8-9 hp per octane point. GIAC-X will not adapt past ~94+ oct. Need race

fuel program past that.

Default I was told by the shop who chiped my car that it would add only a few HP but it would add some.

You need the full race program to take full advantage of it though.

Default Why would they have a race fuel program if you could just use race fuel on the pump program? lol

And how much delicious timing and therefore 'HP' depends on your setup. This creates two variables, so I can't answer that one for you...unless you'd prefer the answer as a DIF-EQ....

Default I dynod 30 more HP at the wheels on race gas in the pump profile after the ECU adapted.

Race profile might give you instant adaptation - but the pump profile will still add in timing and end up getting you to pretty much the same place.

Default I've always heard that it's only adaptable to a certain extent (using octane points as a variable)

Meaning there is only so much timing you can gain on the pump file at a given amount of octane points higher than what that file calls for. I'd be interested to know if this line of thinking is correct or not....I mean your results seem to indicate otherwise.
