Totally worth it for a TTFS tune, Frank really knows these engines.

I got my TTFS tune while the car was stock because I was told it will adapt to the exhaust mods once I get them. But I wasn't expecting much of an improvement with the tune on my stock engine. I was definitely surprised with the amount of power and throttle response I gained after getting the tune on the stock motor. It was very noticeable. Maybe other tunes don't have that effect, but Frank Smith's tune sure does.
Can't wait to see how it feels with a header and custom exhaust.
