Hello all, after extensive research on the Ecoboost performance forums and watching numerous videos online I am considering doing the 1/16 drill hole in the bottom drivers side of the intercooler to drain out any accumulated sludge as I do not have a catch can setup as of yet. I will be working on my 2013 SHO non PP tomorrow with 116,000 miles, and I plan to do a PTU fluid change, trans drain and fill, and new plugs gapped to 0.30 to hopefully help alleviate some surging and p0300 codes under hard acceleration. I don’t believe the plugs or the fluids have ever been done so I’m definitely doing those first. It would appear that draining the intercooler is the next logical step and a lot of people seem to stand behind the mod as long as I plug the hole after I am done draining it as leaving it open would mean that driving through standing water under vacuum could actually intake water into the intercooler unless I am wrong. I really do not want to drill the hole if it is not going to fix my problems but considering my mileage and similar symptoms, it seems like it may be worth a shot. Any input is appreciated.
