Did another inspection of my work and then gave the swapped IS38 some moderately good beans on my favorite stretch of freeway this morning.
On 91 tune, it seems to have the same initial power as the Is20 e30 tune. Except that it keeps going. At low speed, no real difference.
It does seem like the noise after 3500rpm is different. Lower and more throaty maybe? Seems like a more pleasant sound. Placebo?
Will update again after I get the e48 map on.
