Will installing a new fuel pump require a retune?

My walbro in tank pump got delivered last week. Can I install it now without needing a retune or will it alter the mixtures? Im not really sure and would hate to break something.

OR should I get it put in at the same time as the next retune for more boost?

Thanks a lot
Dan

well if it was running out of fuel and was tuned to compenasate for that then it will run richer than before which it would benefit from a retune.
get the whole boost map done in one hit. that way it will save u money in the long run.

Re: Will installing a new fuel pump require a retune?

The air fuel ratios were spot on with the stock regulator, pump and 578cc injectors. I was only recommended to get a bigger pump if I did any more mods.

Ill leave it until the retune with the new cam and ill get the tuners to put it in.

Thanks mate,
Dan

If you increase boost or run it higher than its been previously tuned... YES....

50 : P

Nah Im not really sure. I dont know how much more it can take. Its going strong on 10-12 psi at the moment. I'd like to get a switch in there to run 15-16psi and 10psi.

I dont want anything to break though. Im going to start paying off my loan to get rid of it by june when I have to go back to uni.
Ill likely just put the cam in and leave the boost as it is for now. I wouldnt mind getting my cold start sorted though. You have no problems with cold starting do you?
