I've asked in another thread for some AIT figures from people with the S3 core but nobody has provided me any. If I can see some hard evidence I'd be persuaded to get one.
here's some info on the I/C's avail no figures but having owned an ED30 and fitted the S3 I/C its def worthwhile and I have bought another to go on my 8P. The orig poster on that post had one fitted and he had lower temps but I cant find his post about them.
