what wide-band is the best ? where do i get it ?

R-500 is my choice

 

i got the m-250 with the guage, kinda hard to do if you dont have somethin to log with, but its pretty easy. the plx is my choice.

 

i had the R500 when it first came out.. damn that bitch was expensive

 

yea it is. id say get the m250 and dsmlink so you can log it.

 

I understand, which is more cost effective?

that R500 will pretty much do everything but suck your cock when it comes to tuning

 

DSMlink cannot be used on a 420a, just wanted to clarify that.

 

oops, forgot it was 420a, oook then, a wideband can still hook up to a standalone of another type. but if you arent goin standalone, the m300 or 250 with guage will do with an afc, just have someone watch it for you, you can even do it yourself, its not hard.

 

no one likes the aem or the dyno jet?

 

i was told to go with aem uego wideband....
