lexus maf *not install yet
I just recieved the christmas gifts i bought myself.
1. walbo 255 fuel pump
2. rc 550 injectors
3. greddy boost controler

Basically from your list you can install the greddy boost controler. You would be alright installing the fuel pump as well but no real point untill you are able to get a few more items.

A wide band like the AEM UEGO is not necessary but you do need:

Walbro pump
550cc injectors
lexus maf or the LIPP maf
FPR

Basically by installing the lexus MAF with your 550cc injectors it helps to balance the extra fuel with extra air.

You can leave out the MAF but then you would need a way to tune and the ability to see the air/fuel ratio.

are their any problems if i use that and i dont have anything to adjust the air fule ratio?

You can install the wideband without having anything to adjust the ratio
It is only a sensor so does not effect anything only gives you more information.
