First question is:
Would I be able to get more hp/tq with the maf being on the charged side, since it does meter all the charged air, or it does not make a difference with it being on the charged or noncharged side?

Second question is:
I have a zex dry nitrous kit lying in my garage...It has the 75 shot pill...I was wondering if I would be safe to install this to get a quicker spool and more hp/tq? I have the JWT ecu for 370cc, z32 maf...my hp/tq is 238/255...
Would my A/F's be ok if I do add nitrous? Since it has the 75 shot pill, I should hit the 300hp mark.....let me know...

 

Doesn't matter on the MAF whether charged or non.

Nitrous... honestly I would put that idea right back on the shelf until you figure out what is wrong with your car that you only put down 238whp and 255tq. And once you do figure out what is wrong keep that idea on the shelf, you don't want to put a dry nitrous kit on there. Honestly, you've got to do a bit more reading bro, adding nitrous without adding fuel is the makings of a blown engine. If you weren't aware of this then you've got no business putting something so drastic on your car in addition to the turbo that's already on there unless you enjoy riding in tow trucks and swapping engines in your spare time.

 

I believe I've figured out the problem, a clogged catalytic converter...Well..about the nitrous thing, I maybe using it to cool my intercooler...

 

Glad you've possibly got the problem with your power falling off figured out. Hope that fixes it.

 

big waste of nitrous

spray it into the engine or not at all
