Good info. 30 deg MCT is worth 2-3 deg timing (if tuned for it) which in turn is worth 40-60 hp. You need the xdi hpfp next which allows another 2-3 deg…then start raising the boost…The killer chiller lowers iat2's about 30 degrees on average... I used to average 120-150 depending on temps.... now it's 90-120...
