I have just recived my XEDE and Adjustable cam gears, My current mods are Injen CAI and Full turbo back exhuast with 3 in dp, i have heard alot of things about people having to change there fuel pumps and add fuel rails, is this nessesary for full performance ?

 

Only need to do the fuel pump, not the rails. Usually, we suggest a fuel pump when cams are installed (Stg 1+) but I have seen cases where the stock pump runs out of grunt in Stg 1 levels. Good insurance!!

How much and how big of fuel pump are we talking about?

 

Simple walbro drop-in pump will do. We sell em for $110, IIRC.

Thanx for the info , how long of labor you think we seeing on installing a new fuel pump ?

 

shouldn't take much more than an hour really.

Vishnu recommend fuel pump upgrade with the stage 1+ (cams). Don't need fuel rail upgrade. Stock fuel pump might not be able to keep up with the fuel flow rate at WOT(with upgraded cams). You might need a custom tune for the Injen CAI .

 

Custom tune for the Injen CAI ? explain if you could , and is the Walbro EVO 255 the fuel pump you reccomend ?

 

???

 

Walbro 255 is the fuel pump most Vishnuers use. Xede likes the stock airbox because of the MAF which Vishnu recommends. Alots of times people with different CAI have problem with idling, because the CAI throw off the MAF sensor. If you custom tune then the Xede will work better with you Injen CAI. Vishnu will be able to give you a more technical answer regarding the CAI.

O i thought u guys meant mess with the fuel pump after adding the xede and cam gears, i asked the vishnu guys to program my xede when i ordered to my existing mods.
