Currently running a custom tune on my stage 1+ car. I'm thinking about adding upper and lower IC pipes and the Unorthodox pulley kit to my Evo. Should I be looking to get my XEDE maps fine-tuned, or will these two mods be more or less "transparent" to the XEDE/ECU?

What are your thoughts on the pulley?

Before I take the plunge, I will try to track down the AFRs for the dyno plots that unorthodox has posted for their Evo VIII testing, though.

If i were to add a lower ic + an AMS ntercooler upgrade to my current set up, would a retune be necessary to see the benefit?
Let me know.

If the UR crank pulley is built like proper harmonic dampner but is sized for underdriving the accessories, that's one thing and is probably ok so long as it fits properly. If it's just a machined piece of aluminum with no dampening ability, I won't be buying one.
