Tell Me Again Why Going F/15g->16t I Need A Remap?

[550]

if I recall, rica does free remaps.

The main cause of doing a remap is not only to adjust fueling if need but to also adjust boost levels and the curve. A 18T on a 15G map can be fine if boost levels are down enough to keep things on the safe side and also a mbc to control boost. Also a Stock 15G map has fueling set up for x amount of boost. Basicly you can start out with a 15G map. Lower boost down on the 18T until you have figured out where the best median is. Then from there you raise boost and adjust fueling and ignition to optimize the mix. Base tuning is the most important thing and what i really have people do is DYNO first then get air fuel. Then from there you adjust IF needed which if you want to full make power out of the 18T then you will need to adjust some things.

So with that said it sounds like I should be fine on my 15G BSR chip.

To play devil's advocate:

Why then get a 16T over a standard 15G? Why 19T over 15G if you're not going to reflash?

The 16T has a stronger wastegate than the 15G, the ECU mapping should account for that.

I got a good deal on a rebuilt 16T. 19T is too expensive and is way overkill for my basically stock automagic car. I would still have the stock 15G on my car if it wasn't for the goofy conical housing that is cracked.
