I can honestly say there is no way it feels similar. I sold my 18’ XPT and bought the 2 seat Pro R. My son has my old XPT. In a drag race he gets me out of the hole by close to a couple cars. Yes I reel him in by the end of the drags but not by much. This is a bone stock XPT vs a bone stock Pro R. If your XPT had an EVO kit, than it would beat me all day long. You cant beat power to weight ratio and you know this. Unless your car has come with a new style tune putting way more to the ground than all the previous cars, our cars should run similar with all the dyno numbers we’ve seen. I am glad that you’re enjoying your car. It’s nice that things seem to be finally turning around.
I can honestly say, I have owned both.
The '18 XPT had an Evo exhaust (Captain's Choice), all the boost/intake tubes, and their Stage II tune. But, for a 2 seat XPT it was probably pretty heavy (aftermarket cage/seats/harnesses/comms/pumpers/wheels/tires/etc.). I used to have a build thread on here, but when the forum crashed that was lost, but this has most of it:

I've had a lot of SxSs (XP900 with a high compression big-bore build, stock-ish XP100, '16 XPT, the '18 XPT, a '14 XP4 with a full Z1 setup at 40psi of boost HCR long travel blah blah). I've also had a lot of rails (J35 Buggyworks, SCU Pro Bro with a high compression dry sump LS7 from my old race car, Extreme Double Throwdown with a TT LS1, Poter PX2 with all sorts of various versions of big-cube high compression LSs, BFD Revo with a Supercharged EcoTec, and the latest was a Funco with a 440cui 4.0L Whipple LS7 and an Albins). I've had a ton of fast street cars too (4th Gen Fbodies, super-built C5Z, built '67 Camaro, Trackhawk, and even my current Cayenne isn't slow). My butt-dyno is decently calibrated.
The thing definitely felt way slower than the '18 XPT yesterday. It woke up today, I don't know how else to explain it... and it's still down on RPM from where I expect this motor will make peak HP. For as heavy as it is... it boogies. Doubt it all you want, but I've done the exact same little test loops (or, drying off after washing loops) in the '18 XPT.
