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!

Our good friend Brian drove in from Florida for a Tapout intake, LPFP upgrade and custom dyno tune. He has been running our Purple Belt Performance Package for two and a half years and wanted to maximize his performance. Final results were 616 peak whp and 655 wtq using SAE correction on E68 fuel. This is mighty impressive for a car that now has 158,000 miles on the odometer. However, we were seeing some valve float above 5,700 rpm. Next mods we recommend for this car will be Mace Stage 1 valve springs and titanium retainers.

Kaylee and Jonathan drove in from Texas for the Blue Belt Performance Package. The mods included Green high performance air filters, Gigs ported throttle body, Brisk silver racing spark plugs and Tapout resonated downpipes. Plus we also included one of our carbon fiber engine covers. Baseline pull was 426 whp. JB4 Map 0 put down 449 whp. Map 1 made 503 whp on 93-octane. Then we created a custom map for 100-octane that made 551 peak whp. Jonathan and Kaylee will certainly be arguing about whose turn it is to drive on their 1,003 mile drive back home!

Tim drove his M6 Blackwing in from North Carolina for the Blue Belt Performance Package. After installing Green high performance air filters, Gigs ported throttle body, Brisk silver racing spark plugs and Tapout resonated downpipes, we completed an oil and filter change. Then the car was moved over to the dynamometer bay we starting on the tuning. Peak power increased from 412 to 498 whp, with more power at every single point across the rpm range.

Cleveland Power & Performance is famous for restomods, restorations and custom cars. Recently they swapped 2016 Cadillac ATS-V LF4 engine and M6 transmission into a 1988 Pontiac Trans Am. It also features a Ford 9” rear end along with custom driveshaft and exhaust system. This car originally produced 215 crankshaft horsepower, which would have measured around 194 at the wheels. We bumped that up by 263% to 512 whp for them. Imagine having this much power in your F-body car 35 years ago!
