what you are talking about ?
seems well worth it
RENNtech also has a tune stage putting out more power than the one marketed on their website.

I am currently running this test tune and very capable of making 11s, with a good FMIC (above 93% increased volume), good traction, no meth, no DPs, no DRs.

The majority of tunes on the market need more than just a FMIC to even get low 12's

@OP - Congrats on your new car.....its a lease so I cant really comment on what tune for you to go with and be able to resell that holds it value.
