AFAIK... its only stage 2+ that requires a fuel pump.
But even at stage 2 you may be into fuel cuts, if your oem pump is worn.
Data logs can give you a great indication whether your Stock pump can run happily at a lower stage of tune.
Mandy ,seriously, if your wanting to run a CAI, then you will need to run an uprated fuel pump to assist.
Or like i suggested to you, Run the uprated Panel filter in instead of the oem paper one you had, and that im sure will cure the rich idle condition.
Im sure the guys at Revo, just flashed these cars at Inters, without checking what mods were fitted/never lifted the bonnet, no logs were done after, just "
heres your keys " now "
up the strip you go " and onto the next person.
