Please keep this thread clear and keep it to PMs conceptz.
rx72c I pulled my injectors out and got them flow tested...
Interesting thing is after doing my research the injectors are 720's and 1680cc's here are the injectors i have.
primaries: denso top feed: 720cc, part number: 195500-0830

secondaries: bosch top feed 1680cc, part number: 0280150842

Just wondering if you have any input as to why I had issues with the inital map then?
The primary injectors (2.2 ohms) flowed 48cc in ten seconds @ 40 psi @ 6ms pulse
The secondarys (4.8 ohms) flowed 94cc in ten seconds @ 40 psi @ 6ms pulse
Just wanting to make sure the right injectors are in before I make the 13 hour (each way) trip to get the car tuned. thanks!

Just a shout out to rx72c and Dan S Young. I plugged this map in earlier today (nearly identical engine setup, though Dan's car is far prettier :P) and it ran better than it ever has before, a fact the wideband backed up. Thanks fellas!
It does still fall flat on its face and often dies with any quick application of throttle, as Dan described earlier. This only occurs at low rpm, ie. from idle, not higher rpm so I'm thinking its either the load map before staging or pump settings.
The culprit could very well be the modified throttle body with secondary plates and dampers removed, in any case ill take a stab at the load map tomorrow. Im guessing my 720s will fall somewhere between the first and second maps rx72c suggested. Pump settings are beyond me though!
Any further suggestions or hints would be appreciated, but frankly I just wanted to say thanks!
