i just need to know if anyone has ever ran 150 shot without tune and if held up with just bolt ons, also how many times. i searched but didnt really get an answer. thanks

 

Although I myself lack experience of nitrous, most people claim that anything with greater than 100 shot is strongly recommended to get a tune.

 

NO,DON'T EVEN THINK ABOUT IT...Unless you have a spare motor laying around, well then go ahead and tell us how loud the BOOM was !!!!!

 

+1. From what iv heard from talkin to SMART tuners every 50 shot of juice should be 1 degree retarted I think With my 100 shot i didnt get a tune and I was very scared. So sold the kit bout to buy another 1 and be smart about it and buy a utec before I install

 

good question im also wondering myself im about to install a 100 shot and would like to know how retarded my motor should be hahahaha

 

+1 to what they said... 150 shot and no tune is not the way to go.
