Most end up in the 375-395 rwhp range. The variation is in part because these cars seem to vary in base line dynos. Typical is around 345 rwhp. The best ever on a Dynojet in SAE was 361.
A nonintercooled system adds only 4-5 psi and is fine for a street driven car in a cooler area. The upgrade to intercooled is expensive so the OP should consider that as he decides how much power he wants. You can spend $1k on a tune or $10k on an ESS VT650 so there is a range for any budget but try to think ahead do you don’t backtrack and end up spending more in the long run.

Ess has changes thier pricing on the new sc kits. Not sure everyone knows this as the used market has not adjusted.
On the site a non cooled 550 is $6795 and a cooled 595 is $6995. 625 is right at 8k.
