Looks like it was well past time I run some cleaner through the system every now and then but honestly have neglected it a lot. 165,000 or so miles on these injectors. All were fine operationally but definitely needed a proper cleaning. Decent difference in the results.

I bought the car at 100,000 miles. Since about 120,000 miles it has been run on 93 octane since that is when I added the Karcepts tune. Like mentioned, I have run some BG44k through it a couple of times but should just do it yearly to be honest. Something I had neglected. I pulled them while prepping the car for this season and took them in .
