Does this setup call for bigger injectors: comp 230/236, ported heads with 2.00x1.56 valves ? thanks

Sounds like a need for some 30's to me... Only way to be sure is install everything then logg the car with datamaster and see where the duty cycle is...

Need to find a cheap laptop so I can use datamaster. When I really stomp on it the car bogs really bad...... thanks

That doesn't mean it's the injectors... Could be something to do with your ignition...

madwolf has the 233/239 on stock heads (unported)
and the stock injectors couldnt keep up.
here is the thread:

i was told by pcmforless to up the fuel pressure to 58psi with stock injectors and he would change the injector constant to 30lb. and this would be the equilvalent to #30 injector.
my stock fuel pump good not keep up with that, i was leaning out above 5000 rpm. now i have a walbro 255 and all is well.
