Fueling food for though.
Notice the play on words!
Anyay, we did a local tC on the street and dyno after the kit was installed. He then decided to purchase our Walbro in-tank upgrade, which was a great investment for him.
The long and short of it is that when we where tuning his car, for example at 8 PSI he was needing 15% more fuel through the additional injection map in some areas of the top end. After the pump was installed, the AFRs that WHERE tuned to a 11.2:1 where now 10.0:1 all the way accross the board. We leaned here out, and she basically ended up needing .5% more fuel after the pump was install to get the same previous AFRs.
What does all this mean? That stock pump was starving this car under that power! So we are considering making the Walbro pump an included item in all kits for the future! Cheers!
Figured I would inform the community!

only problem with them is there hit or miss with the reliablity.

yea, ive used a ton, but i have also seen a some fail. for the price you can't beat them. but since there soo mass prouduced, there is alot that slip past QC.
and if you have never seen a walbro fail, you haven't messed with enough cars.

Nice! Adding the pump will cross one more thing off the list that some upgrading will need. Was this something just happening in this car that you noticed or has it happened in anyone else's? By adding the bigger pump could it add power were it wasn't getting enough fuel before?
