Weston from Pennsylvania had a scary engine noise, so he trailered the car in for Jorge and Bob to work their magic. Turns out that one of the timing chain tensioners had broken, and there was no other engine damage. Per Weston’s request, we did a complete teardown and carefully inspected every single engine component. Our Purple Belt Performance Package was included in the reassembly and the car performed very well. It made 504 whp on 93-octane pump gas, and 605 whp on E53. Weston takes this car to the road course on a regular basis, and decided he would rather have a single tune that will automatically scale fueling and ignition timing for any fuel between E0 and E85, so no Kill Tune was created. Regardless, check out how smooth the new powerband is, and how it keeps pulling hard, even past 7,000 rpm!
