My answer to the original question is get a fmic and no dsmlink doesn’t allow you to vent your bov. In my setup with an evo3 I have instant 25psi after 3k. The upgraded 4inch thick bar and plate intercooler with a custom air duct is not adequate enough to cool the incoming heat/air. That instant change in temperature is almost impossible to tune for in my scenario. With retarding timing a whole shitload and spraying additional fuel and reducing boost to 17psi I can run straight 93 with little knock. So I spray meth starting a 7psi and full on by 12psi to eliminate detonation. If I didn’t have such a quick spooling turbo and wasn’t pushing it way out of the efficiency range **I wouldn’t run meth**. > [@woody](#): > > even tho 100 octane is easier and safer to do with a good intercooler setup, its just as easy to keep your meth filled and get a good pump, like the ones mike sells, with a good intercooler. i fail to see how its really that unsafe or a bigger pain. for those who drive their cars a lot, meth seems more practical than buying drums of gas all the time. Its not so much easier but better. The pumps aquamist sells are good and set up for meth but there kit other than the controller, nozzle and pump needs improvement. But they seem to be a good company and learn from there mistakes. Plus they do offer ss braided hoses. Meth can be unsafe as in my case I will see a whole lot of knock if there isn’t a nice glass of meth in my intake when boost comes on. Otherwise byebye ringlands. --- _[View the full topic](https://forums.speedlife.net/t/meth-injection-over-bigger-intercooler/19584)._
