Bigger intercoolers can actually hurt power if your tune isn't adjusted for the 15-20°F temperature drop and changed pressure dynamics
The 3 data points that instantly reveal if your boost creep is from a bad wastegate, tune, or boost controller - most owners check the wrong thing first.
Most people think a dyno tune is just about peak numbers, but the real magic happens in the transient response zones that streetable cars actually use 90% of the time
E85 doesn't just add power - it fundamentally changes your knock threshold and timing advance potential, but only if you monitor the ethanol content religiously
Why the FA24's knock threshold is completely different from EJ engines - and most tuners still don't know
