Im looking to buy a S4 TII that has a street port but is now running lean. The car is pretty much stock except for full exhaust and no emissions stuff. Will Rtek fix my problem? If so how hard is it to set up, can i do it myself? And which one would be best?

 

what else does this car have with it we need alittle more info about the exhaust and any fuel upgrades id do the 2.1 so you can add fuel where its needed

 

Racing Beat exhaust, downpipe, y pipe, mufflers. Fuel and everything else is stock

 

do you plan on any more upgrades

 

Not for a while

 

id do the 2.1 with some 720s in the secondaries and a wide band o2 them youll be set to play

 

does the 2.1 delete the maf?

 

no

 

all we can do is hope they hurry up with that lol
