14-15psi all day on Aseries is alot.. You would have to put some decent gear in one to keep it reliable and handle a good boot here and there. Stock CA's are good for 14-15psi everday and have a few more goodies than Aseries. I think a decent set of Chromie's and rings would be a good investment.
About time you started getting back on here rallycar

...Keep up the Aseries power
