I searched the forums and couldnt find what I was looking for. I was thinking of getting the APR reflash with a chip program and a stock program. Should I get the 91 octane program or 93 octane? Does it really matter which program I use? I usually fill the car with 89 octane gas and was wondering if this would be a problem.

 

It depends on what kind of gas is available where you live. If you can get 93 oct premium then go with the 93 flash and a stock profile so you can run 87 if need be. If 91 is the highest octane available then go with a 87/91 flash.

 

k thanks

 

If you get a specific program...91/93 or whatever, you must use that octane. If you want to use like 89 or something (not the recommended octane anyway, 91 is)you will need to switch back to stock.

 

ya... im not sure why you are using the lowest octane anyways, audi recommends using 91 octane minimum for a reason. but if you must then you must... but if you are getting a chip, im pretty sure you should use the same gas as the chip you get, to 91 chip means 91 octane, 93 means 93 octane...

 

okay thats what I was wondering. Thanks, not a big deal to me to put some better gas in :P

 

You should never have been putting lower than 91 in the first place. Stock program on a chipwon't change the octane as much as it keeps the car out of heavy boost and drives slow, like, ummmm, stock, lol. But that still should be 91 octane minimum.
I don't have a need for a stock program personally. The only thing I'd ever use it for is to remind myself of how slow the car once was.
Some say you should have stock programso you can take it to an Audidealer and they wouldn't know you are chipped. I think that is BS, especially if you've done anything else to the car (like even bigger injectors). They aren't stupid. Unless you go super-sleeper mode and do nothing but a chip, they're gonna assume you've done something if your car even has non-stock rims on it.
I know in FWD 1.8t dub world, we used to use stock program in the winter months, because in the snow and ice, the higher boost programs were too much power and youspin tireall over the place unless you stayed out of boost.

EDIT: Forgot, too, that places out west don't have 93 octane so they have to go with 91. Again, even on "stock" setting, you should never go with less than 91 octane. If you are in an area that has 93 and don't ever plan to move, I'd get 93 and maybe a valet program... but since I'd never let a valet touch my car, I'd go 93 and a race gas file. Which I'm not sure they have for K03/K04 setups from APR.

 

thanks bustanut, love the looks of your car btw its slick

 

93 octane if it is common in your area..busta said the rest

 

so are you saying there really is no way to have a chipped car and take it to the dealer and them not know?
