pipe tuning vs nitro

[Dean Pappas]

Yo Anthony
OK, nitro widens both the pipe length and mixture sweetspots.
Maybe it'll help kill the midrange richness the you had with the shorter pipe.
Of course, maybe you don't need to change a thing, and embrace the new level flight speed.
Ludicrous speed is bad ... hmmkay?

<<<<<    Now I am confused. I am running a little longer to smooth the 
response at the cost of power. I was thinking of adding nitro to give back 
the power. If I shorten the pipe and add nitro will I have to "prepare for 
ludicrous speed"? Or will the nitro help my engines manners?
7800 is not bad but after flying the shorter setting it is disappointing. 
The main factor is the lost of level speed especially in the wind we have 
had lately. Kept wanting to push the stick farther forward last night.
