CT5-V Blackwing Tuning with Tapout!

It took our team more than one year to hit 700 whp with the CT4-V Blackwing. The CT5-V Blackwing should easily cross that threshold next month, on pump gas, only two months into the process.

We did four baseline runs over the last 15 days, ranging from 614 to 621 whp on a DynoJet with SAE correction factor and smoothing = 5. We decided to use the median 619 whp pull as our official starting point.

We installed Green performance air filters, Kong Stage X ported supercharger, Nick Williams 103 mm. throttle body and got 673 whp. Next we switched from the 2.50 to 2.30” GripTec supercharger pulley and installed Brisk RR12S spark plugs with .027” gaps and got 694 whp. All runs were done using 93-octane pump gas.
Next month we plan to add Kooks competition headers, a little more boost and also start testing with ethanol fuel blends. We’ll be shooting for 730 to 750 whp.

Special thanks to Alek from Illinois who loaned us his car to experiment with!

Tapout Tuning CT4-V Blackwing Carbon Fiber Intake!

Our new carbon fiber intake system for the CT4-V Blackwing is a work of art. And it also performs! Internally, this revolutionary airbox design functions in a proprietary manner that increases airflow and boost, without the ECM being aware of the changes. If you bolt this intake to your completely stock CT4-V Blackwing, you will instantly gain 30 to 50 peak whp. Even more impressive is the 70 plus whp gains you’ll have near redline!

These performance improvements take place with no other changes, and no tuning required. Idle, drivability and fuel economy will all remain the same as stock, as long as you stay out of the boost. There are no DTCs or Check Engine light issues. This intake system is safe for any fuel octane from 91 on up. If you’re currently running the JB4, you will need to work with us for some custom settings at the time you install the carbon fiber intake.

Coupled with custom JB4 tuning, you can expect to see gains of approximately 100 whp on 93-octane. Colder spark plugs with smaller gaps are required at this level, and when you add on our downpipes, you can make even more power!

Pricing will be $1,188 for the carbon fiber intake, plus $155 for the Green high performance air filters. All pre-orders will be shipped in February 2023.

Caddy Issues Turbos for the Win!

Mr. X was working with another tuner when his stock turbos destroyed themselves. So he took the opportunity to replace them with some aftermarket ones, but unfortunately, the same thing happened two weeks later. And this time, the impellers went through the engine and destroyed everything in their path.

At that point, Mr. X decided to make the switch to Tapout Tuning, and when we looked things over in person, we realized the damage was catastrophic. We pulled the tune that was currently in his ATS-V to see if there were any clues as to what could have caused this failure. Upon checking out the previous tuners work, we saw that they had completely maxed out the turbocharger wastegate duty cycle table. This no doubt led to the turbos spinning fast enough that they destroyed themselves.

We replaced the long block assembly and Mr. X upgraded to our Caddy Issues turbos. After proper break-in time we put his ATS-V on the dyno so we could dial things in. Final results were a beautiful powerband all the way to 7,000 rpm with peak power of 691 whp while still running OEM compressor inlets. This is one fast M6 ATS-V!

CT5-V Blackwing Green Performance Filter!

CT5-V Blackwing Green Performance Filters are here! We worked in conjunction with Green Filter to design this air filter for maximum performance. Green filters are constructed with four layers of tightly woven cotton gauze, rather than open cell foam. This is thinner, stronger, and easier to clean than other materials. If you look closely at the competitor’s aftermarket filter design, you’ll see they avoided adding the angle, which reduced the overall surface area. By increasing surface area, this design actually increases air flow.

Green Filter uses stainless or annealed steel mesh, which is stronger and allows more intake pressure, compared to the competition which uses aluminum instead. Green’s filter oil is 100% synthetic, which is safe for all engine sensors. The oil provides a positive magnetic charge, which attracts negatively charged dust, trapping particles as small as 5 microns. Easy to install, clean and maintain. And the cherry on top? They’re made right here in the good old U.S. of A. and we couldn’t be happier about it!

Blue Belt Kill Tune!

Normally when you hear ‘Kill Tune’, you associate it with our Purple Belt Package. However, in the case of our friend Jason in Tennessee, he wanted to take a different approach. Last year at Cadillac Attack, Jorge installed a fuel cam in the parking lot for him and that led to some impressive times on the track. This year, he was eager to push things further.

We connected with him for a Remote Dyno Tune so we could see how far we could take his ATS-V without the use of ethanol or methanol. After multiple pulls to dial things in, final results were 619 whp and 686 wtq on race fuel! That’s impressive on these cars for sure, and Jason plans to go further by installing an upgraded LPFP so he can put his car into the nines!
