hey al, i have now walbro fuel pump, hallman mbc set at 21psi, do i need a reflash??? and is setting at 21psi absolutely safe???

 

I would have to say you would see some gains, you are probably running a little rich now with the new fuel pump...

 

Are you saying you had an old flash that was for the stock fuel pump?

If so - then yes you need a new flash

 

then how much would it be and what's the approx whp am i looking at, al?

 

do you now have a custom tuned flash or a base flash ?

 

i have a base flash

 

$100 for an upgraded base flash plus shipping

UNLESS you can wait till I come to LAon Jan 21 & 22 - then it would be only $269.99 for a full 2 hour custiom tuned update = but you must have your deposit in my 12/24 to get that price - thanks
