You guys got 69 whp out of a freaking GT3?????

Getting power out of the high strung Porsche GT3 is very tough but not impossible. You need a quality tuner and @Tyler@APR is about as good as it gets. He proves it time and time again and this time APR worked their magic on the 991.2 GT3.

Details below but software only gains at this level with support for multiple octanes and fuel types is just what sets APR apart from the rest.

No-brainer upgrade for GT3 owners who want to remain naturally aspirated (and most do):

The factory tune was really lumpy, and thankfully E85 was doable and passed emissions. Always awesome gains to be had with that fuel!

Ok, that's it, I'm trying the E85 file.

Even larger gains and both releases back to back.

Slow down guys... lol

Let me space these out.

Hah, don't forget the turbo kits we released yesterday too

[F16HTON]

992 base to S/GTS upgrade?

[Arin@APR]

We technically have that now, but not released.

It should be ready along with our stage 1 and APR plus tunes for the base model (which is on the dyno now).

Thank you Arin, I'm patiently awaiting and will program my car on day one.
