You’ll want to do the DD mod while your ecu is sent off. Basically you’re doubling your clutch springs. You’ll want to get the retainer also that keeps the springs in place. Tim used to sell that as a kit on his website. It comes with a gasket, extra clutch spring, retainer, and clutch bolts. The extra power will slip the clutch. Yes third gear burnouts are achievable with the flash. 120mph while spinning…. 98mph after it caught traction…. Bouncing off the rev limiter in 3rd gear. I would have tried 4th gear but I had a corner coming up. Tim’s (gurued gear) flash eliminates the sluggish feeling in 1st and 2nd gear. It’s restricted to a certain power limit until you get over 40mph or 3rd gear. (I have read.) he can also turn ex-up off to. There are cables that run down to the catalyst. You can either remove them, or just tie them up. But having an exhaust it should be done already. If it’s been flashed by Tim it’ll have a red sticker on it that says “off road use only.” “Gurued gear”. If you keep the PC-V and take it to a dyno they can fine tune it for maximum HP. I have got to get this done on mine. His flash also raises the rev limiter, and raises the speed limiter. You won’t be disappointed.
