i got a custom tune dynoflash 2 months ago and out of noware my walbro 255 decided to take a poop and stop working. well got a new one in and it seems like it is running richer than it did before. my theory is that the old pump wasnt running efficiently and ended up causing failure. now that the good pump is in it is sending more fuel than my car needs help me out AL

I had a similar condition with a tune I had with a failing pump, when I insalled my Walbro the compensation the tune had made for my failing stocker made my car fall flat on it's face in the higher rpm's.

 

JUst curious but what are the signs of a failing pump. Does the whine get louder? car won't start?

Thanks

 

the sign i got was car died then would not start. replaced with stock pump and she purred like a kitten

 

Please gie me a call - I am confident I can resolve your issues with a through the mail revision

 

there is a possability that i will be coming to chicago with my buddy for his custom tune. i really dont want to get a mail in revision because that would just be a waste of my custom tune. i called you last week but i guess you were busy bit ill try agian tomorrow. Thanks

BTW im going to hook up a wideband to see what my A/F ratio is. according to me Apexi turbo timer im filthy rich i know it isnt accurate but it just flatlines to 10 where it ran higher before.

 

Narrow band 02 is useless

A new custom tune is a good idea - under the cirumstances I will offer you a disconted rate
