My car lately has been throwing a CEL and when check the code it says its too lean....Ive had a eflash from dynoflash for over 6 months but this started to happen lately.....does anybody know how to fix this where should i add fuel at.

 

Call Dynoflash for starters. And buy a wideband for sure. Or stop by a shop with a dyno and have them check your AFR. And turn boost down. And put some race gas in.
