We offer tunes in 87-89, 91, and 93. So your best option would be to get a 91 octane tune. We do not offer a "race" tune, but our Performance TUne is the most powerful tune we offer.
Tunes can take up to 3 business days from when you make the purchase and submit an MPT Tune Form.
We have not tested a tune from that company, so we cannot tell you the difference between their tune and ours.
