Best "Bang-for-your-buck" 2021 tune

[FlynnZero]

Get a JB4 and a custom tune with it with your mods. It should give you a noticeable increase in HP and especially TQ with your supporting mods, especially if you go flex fuel route. A company has shown proof that they have cracked the new Bosch ECU but they are not releasing it yet until they can protect from other tuners stealing their work. There are rumors of September but we will have to wait and see.

They better not wait too long, others are working on it. Be sure of that.

93 octane 425-450 whp
E50 475-500 whp

Buddy has a 2020 with CTS catless down pipe and bootmod stage 2 on 93 octane…. will the 2021 with 50 extra HP from factory get the same net result or better?

You can expect to be around 450whp catless on 93.

Are there any numbers for e85 with stage 2 ?

E85 will net less power than E50 without supplemental port injection fueling.
