PFS purple, large injectors and high flow turbo's
 

Hi
I am thinking of upgrading to the M2 high flow turbo's. I have a PFS purple computer. I need to get larger injectors, lines and fuel pump. Will the computer still work with this and what settings would need to be altered. (I have Large IC, intake, DP already and don't want too much lag or the hassle of a single turbo kit.)
Thanks

You can run larger injectors on the PMS (Purple comp) as long as you maintain the ratio that the stock 550 primary and 850 secondaries have to each other.

Do get the car tuned after that - I don't think you'll find maps for the PMS with larger injectors anywhere....

Are 1300 and 850's ok. Will this affect anything else on the car or drivability with the larger primaries?

850/550 (stock size) = 1.55

1300/850 (your size) = 1.53

I guess these are close enough to work fine. I believe that you may have some issues at idle with those large primaries; you'll have to take out a lot of fuel at idle.....

Perhaps a tuner will be able to help you!

for your 850 1300 combo start off at -30 on everything but the boost table, maybe around -30 to -44 at idle.

It works fine.

you may also try 550 1600 combo I've done it it works most of the adjustments will have to be made on the boost table, that is where staging usually takes place with the stock ECU, make all necesary adjustments there

we made 470 rwhp on a single turbo with this unit at 1.5 bar
it is quite capable of supporting big power it just gets very tricky to tune above 17psi because that is all the map sensor can read.
