Lets see if I can help ......
Safely???? What does that mean?
With a proper tune (As mentioned) on a perfect day with perfect conditions ..... SURE!!!! 100%
Now here come the "But".
BUT .......
What if your bottle pressure just happens to be sitting at 1100 instead of the 950 you had it tuned at? More bottle pressure = more air = lean.
OR
Perhaps bad air (good air = bad air - because you will gain HP)
Or, lets say the pump fails for a second ...... or your fuel tank is a little low ..... or you detonate because of bad gas ....
The point I am making is that if ANY of these happen on a 150 shot with stock internals you are going to think it's the 4th of July.
a 75 shot on the other hand is MUCH more forgiving ........
NOW That being said..... with a proper tune and a REALLY good set up (proper pump/pumps/injectors/warmer/window switch/fuel pressure cut off/WOT switch/ and any other bells and whistles I forgot to mention), you are likely to be OK, I just don't want you to think it's "no problem" and then have you blow it up without being told the whole story.
Just do it right
