Okay I just wanna make sure this is normal, I installed the 720ccs and my car seemed sluggish, didn't throw me back like it used to when I droped it into 3rd on the freeway, my dad was driving behind me and said he smelt raw gas, really really strong, I turned down my first gen safc 4000, -18, 5600, -18, 7000, -16, and it revved fast all the way through first and second, but when I droped it into 3rd going 65mph, it still didn't throw me back like it used to... please tell me I just need to get my **** tunned, which will happen once I get my new SAFC, so I can set high and low throttel, and hopefully get my water injection worked out....

 

Sounds rich. Larger flow injectors do that without tuning. What is your air/fuel guage showing?

 

Yikes you have a walbro too. Make that reeeeeaaaaaalllly rich.

 

yep, feels more torquey, but less hp, yeah my a/f gauge be showing rich 95% of the time.............

 

Lean out your fuel controller, skippy.

 

Flow does not affect the amount injected. Only rail pressures, injector sizing, and duty cycles affect how rich a car runs.

In this case, it is sizing and duty cycles.

 

Try new plugs. They may have fouled.
