curious on the mods i can do for low end power

i just instaleld test pipes and a y pipe i feel like i lost alot down low(is this prossible or jsut me)

when it comes to low end power i think of
cams
headers

anything else thanks

 

I would get a spacer next. It will raise your whole band up and you should get your power back. I would go with the spacer the G35 guys are getting. I read nothing but good things about it.

 

i woudl but i already has teh crawford cast plenum

 

oh sorry, I missed that in your sig.

This is inaccurate, aftermarket Cam profiles and headers in general seek to increase power towards the high RPM band, not down low. If you seek to improve low end power and tip in throttle response , you should try options such as a 3.9 rear ratio , UR pulleys , slightly lighter flywheel.

The plenum and spacers improve high end at the slight expense to low end TQ ,as do most of your mods so far.
