I have a stock LS1 with flowmaster exhaust and a short throw shifter. What is the safest shot I can run on my car. I have 129,XXX miles.

 

Safest would be 0.

however you will hardly feel a 50 shot. a 75 doesnt do squat to the motor as long as its tuned. as long as you can tune the car and make sure you track A/F a 150 shot is just fine

 

lol wat till nick hears this lol i have heard 125 is the safest and thats wat im doing and u can feel a 75 shot no problem and the track times will show it and a tune is not needed u have high miles so i would have to say it might be a bigger risk but its all up to u... and i would talk to some pple that know alota about it like nickdotcom he is pretty well educated on it all and he is the one helping me out.. i bought a kit with every safety part i could buy and a bottle heater and still didnt spend over 800 bucks so i would check out dynotunenitrous.com...

 

lol, i meant the 75 wont damage a motor, not that it wont make u faster.

 

ok lol i was like here we go agian lol
