So after reading everywhere about how incredible Techrons fuel system cleaner is (not their cheaper fuel injector cleaner) I decided to put some in my tank two days ago on fill up (20 gallon treatment).
I was experiencing some rough idleing prior in the SRT, but I know compared to typical cars they do "rock" (shake the car) more due to the cam according to SRT.
Anyway, mine felt as if it was rocking a lot more than usual\not very smooth, I could easily feel the car "shake" me when just sitting in traffic, so basically idle in general, driving otherwise it was perfect. So far I'm about half a way through a tank maybe a little more, and WOW. In traffic it idles SO much smoother now, before it felt like a rough cam kinda going down and up down and up with or without A\C, it just seems to run so much smoother now and the treatment isn't even done.
I waited until my tank was pretty much completely empty, then poured the Techron in, then filled up with 93, then drove it pretty hard, I'm still amazed at how quickly I have noticed a difference, maybe it just sucked up all the Techron at the start, either way, USE THIS STUFF, clearly people aren't making this up.
