My question is pretty simple just like in the topic description if anyone ever used these 42LB bosch injectors (#0280155968) in their GTP? I been deciding to in the future going with a VS cam and ported supercharger in my 2001 GTP for my new mods,so these injectors would be supporting mods. I noticed that these green bosch injectors would be the same plug/play as our 36LB injectors just bigger in CC and LB/PSI. So in regards to tuning I believe it would be more of a challenge than Lucas 42.5LB, but I always am a firm believer that anything is not impossible especially since we have a tuner. Let me know if anyone has used these particular green bosch injectors and what troubles, if any you have experienced running these injectors.

EDIT:I need injector settings for these injectors and the reason why being that these are different from lucas 42lb injectors. Thanks.

Part Number Delphi 01D030B
Static Flow Rate: 42.29 lb/hr @ 43.5PSI (300kPa) or 320gm/min
Static Flow Rate: 48.83 lb/hr @ 58.0PSI (300kPa) or 370gm/min
Dynamic Flow Rate: 9.96 gm/pulse - 2.5ms pulse width and 10ms repetition rate @ 43.5PSI
Coil Resistance: 15.9 Ohms / High Impedance

do you have this?

use either 43.5psi or 58psi, the tables will come out the same.
 
Thats IFR.

Which is the same value for every column if your FPR is doing its job.

Our PSID is 3.5 Bar, all the time.

Which makes that spreadsheet pretty useless.

What about offsets?
 
Lets get back to my question. Anyone willing to answer my posted original question to my thread?

I have tuned these before... they are a bit bigger than the other 42's that I usually dial in aroudn 39#. Best way to tune injectors is just guessing then adjusting after you scan...

If you must do it in 1 shot, then multiply IFR by 1.23 in HPT or 81% in DHP.
