What happens here

After a series of test drives and tuning adjustments, the engine still has some hesitation during 'tip-in' (initial throttle application) and the cooling fans are intermittently disconnecting due to loose wiring. The next step is to perform a full-throttle pull to assess high-load performance and identify any further issues, particularly with the 4L60E transmission, which is known to be a weak point under high power.

Goal: Assess high-load engine and transmission performance.
