Ended up trying out the new apr coils available for sale for cheaper then oem replacement. Im at 105k miles and figured it would be worth it to replace the original coils and figured id give theses a shot since not much info out there for user experience.
Im curently running EPL stage 2 single pulley (187mm crank 2.95 ratio) and have been running stock plugs gapped down to .026 as recommended by tuner ( changed out 12 months ago 10k miles so not old plugs)
I remember back when i had a s4 2.7tt when i did the icm delete i was able to make the spark plug gap larger for a cleaner burn with the "r8" coils so i did the same here with the higher output coils and gapped the new plugs to .028.( may experiment with .030 if i have time)
I noticed right away the idle seems much smoother, and driving i felt that the throttle response improved and got rid of a hiccup i had once in a while at 6500 rpm. They also improved and my mpg, went up by about 2mpg average per trip . I even saw a high way trip of 33.5 mpg at 68 mph average for 20 miles when before would be closer to 30.
