Engine ticking or knocking sound. I've heard this or have this in my engine. Almost sounds a bit diesely (if that's a word) This I've heard even before mod 1 was done to the car. To me, the engine sounds weak under the hood. I miss the big cam sound I guess.

Sounds like the fuel injectors.
Have you been dropping 91 octane in there?

Yes, since the retune I have been filling w/ 91. At least that's what the pump reads. I do notice the slight hesitation in the pedal at times and I hate that.
Oops, make that 93 octane on the above answer.
