i've been thinking of trying out a 75 or perhaps 100 wet shot. My question is, with taking some timing out with the tune to work with the nitrous and not blow anything up............if im not running the spray (turn off via switch) and i stomp the truck using only motor, how bad of a difference will i see being i will have alittle timing taken out? very noticable?

 

it should be a minimal difference for those size shots.
heck i ran my best n/a pass with tr6 plugs and a tune that i can safely run a 75 shot on.

 

if your not going to go past a 100 shot i wouldnt even worry with a tune imo. i ran a 125 shot on stock tune with no problems.. just some tr6s and go spray thats me though..

 

but i plan in bolt-ons still with a 75 shot most likely so tune is needed

 

I'm running a 125 shot with tr6 plugs and 28 degrees wot timing with no issues, been running that for awhile now. just make sure your a/f is tuned to 11.5-11.9 and you should be golden.
