I switched from Stage 1+ to Phearable 1.5 (NOT R) mostly because I was tired of hunting for 93-94 octane. It's not readily available in my area, but 91 is everywhere. I also heard that Phearable 1.5 was way smoother than TSP Stage 1, so I figured let's give it a try. Honestly while there is...

3 weeks ago I installed MAPerformance street exhaust on my coupe and couldn't be happier. I'm also keeping stock dp /fp. The sound is just perfect, I get gurgles when shifting 1-3 and in reverse. I didn't want anything too loud and this hits just right, it can be quiet when just cruising but...

This month I installed the Procivic TR Lip and MAPerformance Street exhaust!

That's my exact setup!

Hey any chance you can post an update on Stage 1+ vs 1.5R ? I'm currently running 1+ and love it, but I want to try 1.5R just for the hell of it.. worth it ?

OP we need an update! Interior pic ?!

You can get Procivic lip in Canada but not BaysonR (not easily). That's the only difference. I'm rocking the Procivic ;)

Fair enough. I've had some lemons before where the issues were just too much, but I can't see myself NOT liking this car even when the eventual wear and tear sets in.

Installed last night thanks to this thread and couldn't be happier! The turbo sounds GREAT, my IAT dropped a bit and my fuel trims basically stayed at 0% after I drove around for a while. Good stuff!

I've had my 2020 Si Coupe for just over a year now with zero issues, I freaking LOVE this car. But this thread scares me for potential issues down the road ;(

I've got sequential side markers; to find the right wire to splice into you can unplug the harness from the headlights, turn on your blinker, then touch the side marker's turn signal wire to the metal prongs inside the harness 1 by 1 to find the correct one. When it starts blinking you found it :p

I just flashed TSP stage 1+ on my stock 2020 Si this week and it's 10000% worth it. Honestly for just street fun I personally don't need anything more than that lol. Although I did install a BMS intake today just for the turbo sound ;)

I just flashed TSP Stage 1+ (2020 Si) and noticing some bogging/bucking in higher RPMs. Not sure if it's the same thing you guys are talking about; in any gear if I'm over 4k RPM and I let off the throttle there's a slight buck (that's no big deal) but when I get back on it there's a delay...

Ouch 0_o

Just hit the gas while stationary in neutral, your RPMs won't go higher than 3k by default. You can adjust this by pressing down the clutch and hit cancel although it reverts back to 3k at startup

Finally received my KTuner from TSP in the mail a few days ago and flashed Stage 1+. Being my first time doing anything like his the process was easier than I expected, but I do work in IT for a living so it wasn't hard to figure out.. Tweaking the settings and the LED lights (for V2) is super...

Man you guys are killing me, my KTuner + Stage 1+ shipment is "mia" :( Waiting for TSP to figure out what to do.. I can't wait to try it out !!

Great thanks! I fully filled with 93 (well, 94 actually..) but my order isn't in yet. It'll be here in a week (hopefully!) so it gives me time to drive out the leftover 91 and refill with 94 again :P

Hey guys, stupid question.. I've been filling my Si with 91 since I got it. I just ordered TSP Stage 1+, what's the correct process to switch to 93? Just drive until gas light comes on, fill with 93 and I'm good to go ?
