So i have a db ls turbo. Running 6 pounds on a t3
T4 .50 trim. My question is i have stock fuel pump that i was tuned on. Now i'm going to upgradr to a walboro 255. The tuner said i have to retune but can i drive it for awhile before i retune? I dont want to keep retuning it because i want to change my exhaust and my clutch and raise my boost. So i want to retune it all at once. so is it ok for me to just run it with the 255?

It would be fine to drive it for a while with the 255 in there. Just dont beat on it and keep a close eye on your A/F ratio. Yea pretty much anytime you change anything, you will need to touch it up

good luck

I think u don't have to retune he's adding a bigger fuel pump u might run on the rich side ur getting more fuel to the rail the injectors are gonna give u the same amount of gas it was tuned for adding exhaust if it was tuned without it now you install exhaust the car with have more back pressure it will lose some power but agian u will be on the rich side

I'm srry but if ur upping the boost yes u will need a retuned but ifu leave it as is same psi and change the pump u don't need a retune
