HEMI Hump Day!!!
This gorgeous '70 Plymouth Road Runner made its way in with a 392ci crate motor mated to a Tremec Transmissions TKX & wasn't running properly with the previous calibration. It was having some issues of excessively backfiring while decelling.
We did a baseline run, & could see it was running leaner than we'd prefer to.
We got the Modified by KC calibration dialed in via HP Tuners, & the byproduct was additional power as well.
We picked up an extra 31whp & 26wtq!💪
Vince is super pleased to get rid of the popping/backfiring while decelling, & no longer running lean
🟥 : Baseline : 416whp/448wtq
🟦 : MKC : 447whp/474wtq
