Honestly, I don't think those three mods will lean out the car enough where it will be a big issue, but then again, thats my opinion. It doesn't sound, from your choices in mods, that you are very tight on money, so if you CAN get the tune, definitely do it...someone else had very good results with it.

Other than that, it's useless to get a tune.

TT and SC is a different story...
