I had a 420a and it was a hunk of crap. I did a lot of looking at the possibilities when I had it and when it came right down to it, the $1400 is more than twice what I paid for my TSi. And in the end, the 4g63 was a lot easier for me to work and and figure shit out on. Then again, 95% of my friends knew them inside and out, and so it was MUCH easier for me to learn like that. I look back on it all now, and I see that my 420a Talon was an excellent way for me to get hooked into these devil cars. It was SEXY.. I mean come on... But it wasn't fast and it would have taken a lot for me to make it fast. It would have costed about the same as just buying a decent 1g AWD! Plus 8-10 psi isn't that great. I was hitting up to 16-17 psi in the stock TSi after her turbo was replaced
