I will tune eventually I'm just trying to do it the most cost effective way and safely I hope. But I will buy a boost pill and cutback when I go in for the tune.
If you are going to bother with any mods then you might as well get a tune. The only real way to properly tune the engine is with a boost pill. Which is a restrictor which help build boost faster and hold it longer making it more stable for tuning. Stock pill has a bigger hole which bleeds off boost faster thus is only capable of lower boost levels.
