yes! Bc if not u take the chance of hitting rev limit with your nitrous still spraying. Not a good thing!

 

That's what im afraid of

 

evrything stated before is right man....even though i have seen people run up to a 125 shot a couple of times with no adjustments from a motor tune....i would not do more than a 100 on a motor tune but like stated before making sure u ar enot leaning out or running ritch check the plugs every time

 

Hey you ever go to Dothan Dragway and run your truck?

 

I havnt yet... i actually built the motor about a month ago and put 1.5k miles and changed the cam again... i only have bout 1k as we speak on this setup! i used to run my quad and dirt bike down there though and i go watch the roundy round cars in the dust bowl from time to time!

 

if i have my shifts at 6800 should i set my window switch 3000-6700 or 3000-6800 i want it to start spraying at 3000-3500 but should the cut off be b4 the shift or on the shift?

 

I have NGK TR6 plugs and walboro 255 and about to send my ecu to wheatley.... can i run factory fuel regulator on the rail with the 255? are the TR6 plugs ok with a shot if i watch for lean/rich on the plugs?

 

Good luck with those tr6's... Mine didnt like the 100 shot

 

FIRST... Def run a window switch, not running one just cost me about $2800 to fix my motor

Also I used to run ZEX plugs 1 step cooler but I am trying TR6's with a 125 shot, not sure what is going to happen... 2007chevy5.3l... What happened to yours??? please share.

Also with that Walbro pump the stock regulator should be able to handle the extra return flow but I would absolutely run a fuel pressure gauge to monitor while spraying...

Also, I shift while spraying all the time with a trans that I built.

Just think of it this way... $500 for window switch and pressure gauges compared to $$$$$ to fix your engine, take my advice, I learned the hard way!!!

 

How did not running a window switch cost you your motor?
