AFAIK S63TU has a bit larger turbos (but not overly so), larger Intercoolers and a crossbank intake, different oem tune obviously.
We can also look into possibility to swap X5M intercoolers or ones from M5 maybe. Another even cheaper option is to install meth kit - it will lower IATs even more than bigger intercoolers (plus will raise octane to allow for more timing - which will yield more power gain). Also, heard that meth cleans valves and pistons - especially needed for our direct injection engines - but not sure how true it is. |
Hmm doesn't seem like enough to get over a 100 more ponies. Anyone know what PSI the M runs at? Stock 50i is like 13-14 right?
