Around 50 bottles through my old NX wet kit in my LS1. Only a few bottles were on a 150 shot. The rest were a 100shot...stock fuel system, stock motor. No problems and 45K on the clock.

 

Bought my car with 59K miles on it and my 2 first mods were nittos and NX Maf kit. Went straight to the 150 shot (used 175 shot on several occations). I now have 78K miles on it and have been through 30-45 bottles. Stock fuel system and tune.

 

No way in hell I could ever guesstimate how many I have been thru. I suffer from low bottle paranoia, gets down to around 10lbs, and it HAS to be refilled.
