Drag racing may not be your thing...but....I actually did a real life timing run pre tune and post tune..the clock don't lie so the tune is legit not hearsay..real data!!..this was needed to show people the tune is real...and worth paying for..the 1/8 the pre run was 8.829 sec..at 74 mph..post tune...1/8 track my time is 8.497 sec at 85 mph!!..and I wasn't trying...I know it will do 8.450 or less.. this here is what people need to see..this is stage I ...I can imagine stage II.
