Hondata can add 66 hp and 120lb-ft torque which would make it produce more tq than both your old cars and similar HP. They look way way better and built better than the Q50. I see no downside.
I have over 10k small pistol primers and 4lbs of Vihtavuori N320. I used it for light recoil 147gr 9mm. Super clean powder. Let me know if you’re interested.
When I raced SCCA I had some Motorola gear so I could have a spotter. Never registered or got a license. I programmed it myself and just guessed on some frequencies.
