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!

Jason from Tennessee is running our Blue Belt Performance Package plus fuel cam. He wanted to see how far he could go without ethanol or methanol, so we connected for a remote dyno tune. Final results were 619 whp and 686 wtq on race fuel. Next Jason plans to upgrade his LPFP and put this car into the nines. Stay tuned!

Steven from Ohio originally chose to work with one of our competitors. However, things got expensive quickly when his stock turbos destroyed themselves within just a couple weeks. He replaced the turbos with some aftermarket ones and the same thing happened less than two weeks later. This time one of the impellers went through the engine and completely destroyed everything in it’s path.

Our team offered to help and took the car in. We have tuned hundreds of these cars worldwide, and have never seen turbos come unglued like this. When we pulled the tune, we noticed the previous tuner had completely maxed out the turbocharger wastegate duty cycle table. If you don’t know how to tune with finesse and turn all the knobs up as far as they will go, you can actually spin the turbos fast enough to destroy themselves.

We replaced the long block assembly and switched to genuine Caddy Issues turbos. After the engine was properly broken in, we spent a day on our dyno working up one of our famous calibrations. As you can see, boost and power are now smooth all the way to 7,000 rpm. Peak power was 691 whp, still running OEM compressor inlets.
