E-tune 200$
https://www.xero-limit.com/custom-tune.html
I’d rather have an E-tune from one of the few reputable shops that specializes in this platform and has E-tuned 100+ of these cars with numerous different setups/mods vs a random dyno tune from a shop thats done 10-15 or less.
E-tune vs dyno tune both from a reputable shop the e-tune will be 90% as good for 40-50% the cost. Usually with the E-tune being slightly on the conservative side so should be equally as safe. You just might leave 1-2whp on the table when NA or 5-10 when FI.
