Can someone help me out calculating for the 36lb GTP injectors. My stock IFR is 22.27 across the board. My fuel pressure is 48-50 psi at idle. I think the GTP injectors are rated at 48-50 psi at idle , so do I just divide 36 by 22 and then mutiply that by 22.27. I got 36.44. I think it is right. I know I'll have to do some fine tuning. Thanks Steve

Do what I did. Go to the bin depository for HP Tuners. Find a GTP bin. Copy and paste the table. Worked great for me.

The stock 98 GTP flowrate Vs. KPA

from 0-100vac
steadily increases from 36.1 to 38.4 across the band.

If you were N/A you would want a steady across the board fuel maybe, like out stock file, but with the charger you'll want to do the same thing GTPs do and steaily increase if from 0-100 vac.

I would copy the stock GTP one and log runs, then edit from there.

36.1 36.51 37.03 37.76 37.91 37.99 38.04 38.1 38.14 38.28 38.4

That is the stock values from 0-100vac for a 98 GTP.

Damm, your maxing the 36lbers. What is the max hp of the GTP injectors? How much hp and tq are you putting out?
