ok...so seems like the octane booster worked, highest k/r i saw was 3.8 and that was because it was shifting from 3-4. but the rest of the pulls were in 2nd from 2500-5500 and the highest k/r i saw there was 2.6. so im guessing the rest is because of these bosch plugs...so do i have to run a octane booster all the time now? and dont worry, i didnt just slap the octane booster in and wot it..lol i drove like 10-15 miles before i started testing, so pretty sure it working.
