Awesome stuff... assume clutch etc can handle the torque increase as I know when I had my Saab, luckily I had the Auto which can take nearly 500lbs of torque but the poor old manuals could only handle around 390lbs... so all manuals had to be reigned in (2.8 V6's). Not sure what the specs are on the ST but I've always had a soft spot for the ST's and the RS (although more from the ST) as all I hear id bad things about mapping RS's? So many just crapped out etc, especially around the 2017 era...Had the Motorsport Developments 280bhp remap installed on my Focus. A modest 30bhp up from standard, but quite a considerable increase in torque - from 260 to 340 lb-ft. It's transformed it. It pulls quite a bit harder in every gear, especially at motorway speeds. 3rd pretty much feels like 2nd, and full throttle in 2nd is strictly a dry weather activity
It's added even more of a fun factor to how it drives, and I love it.
Nothing better than free performance though... when I had the V6 Saab 93, that went from 256bhp/252lbs torque to 318bhp/444lbs of torque and it was like a completely different car... shockingly differently.
ENJOY!!!!!!
