if i got my car tuned n/a on 93 octane with 27 degrees of timing would i be able to run a 150 shot if i use 110 or 116 octane gas without a retune. the motor is a forged 408

 

If I am correct.. someone correct me if I am wrong...
But wouldnt you want to tune the car for the nitrous at WOT. Plus if you tune the car you can tune it to run that 93, and work fine...
But as for being a 150 shot, I would personally put the 106 in to be safe....

 

Its hard to say. Uping the octain will help but you will probley need to still pull some timming.

even though its a wet kit
