as said above your stock tune is in a different location. "load tune" should have all the modified tune files. should have another option to "return to stock" or "load stock".
went with upr adjustable on mine. no issues with install other than lack of room or issues since installing them. lowered the motor slightly while i was at it.
i had some of those i think. they were ok. not great def got some wheel spin with them but i never felt unsafe. lasted a good prob 25-30k miles. i think mine were higher speed rating tho maybe 103 or something like that. for 100/tire not bad.
No tune required sends you a pre programmed maf sensor. No other difference. Tune required you just reuse your stock maf but need the diameter of the intake tube accounted for in the tune.
no tune required intake but was tuned thru lund. it def seems to be one of the better flowing intakes forsure i just didnt really love the way it felt.
intake tube was for 15-17 and works fine. i reused my stock TB. i personally did not like way it drove with the pmas. car felt too twitchy with the pmas for my liking.
i ran pmas before but didnt really like it but that was on a stock IM. now with the 18 mani im running mishimoto intake tube on stock box with drop in filter and i like it a lot better.
