who's done the gotts mod?

I think the people without a tuner see a lot more gain than the ones with.

 

I've heard it doesn't make a difference and I've heard it does make a difference. I think it just depends on the truck and what you have already done to it. this is the first mod I have done to improve performance on my truck so I guess that is why I noticed a difference

 

i did the gotts mod a couple weeks after buying my truck, wasnt impressed with it, so i got the k&n system, took 20 mins to put in, i was really happy with it, i got a noticeable gain, only thing that sucked about the k&n was it coasted almost 300 bucks

 

it's not an incredible gain but it was noticeable
