Need some help with this check engine light problem
Got on my 1998 pretty good the other day after doing some mods and shortly after that the check engine light came on. Took it to my mechanic and he did a scan and came up with a code PO174 lean Bank #2. Fuel trims both banks 22% adding fuel idle and running. Mods added were Blackwing filter, 1000cfm MAF, Carbon fiber bridge and SLP exhaust. He says the computer was asking for more fuel when I got on it but couldn't deliver. Has anyone had this problem and can you tell me what I need to do. Thank you in advance for your help.

Isn't there a fuel pressure regulator or something I can change to give it more fuel when it wants it to match the increase amount of air it is getting? Alot of members have changed their MAF's on there vettes. Is putting the original back on the only solution and the MAF is a waste of money?
