Went on a corvette run from SLC UT. to jackson hole wy...........54 vetts....way fun.......anyway, up logan canyon were @ about 6500 elevation and coming up on a semi..........my turn comes to pass...........my personal fav........passing anything......temp is about 70...hit it and bog, run, bog, run, and so on.........I'm thinking........wtf.....and then it hit me the meth injection is doing it........stopped and unhooked the system and then found out c-6's are delicious.........anyway a heads up it your hitting the mountains..........I unhook it this time of year anyway.

but why would it couse something like this ?

does seem odd to me as well. How is your injection system controlled? Only under boost I assume. Do you also have an air to air IC to control heat with your injection system off line?

would a smaller flow nozzle be a better solution?

Too much meth and not enough air?

At high altitude your going to run richer with the meth injection (thin air)....with any car.........I'm tuned on the rich side anyway and am using the meth in place of a intercooler........the meth injection system was flooding me out....no spark........it runs fine in the high summer heat at lower elevations......I could install a smaller nozzle but with winter coming on I don't need it.....I was just trying to make the point that traveling with the system, even in the summer you might see the same results at hight elevations..........it turned into it's monster self after I unplugged the snow system controler..........and I think I will go smaller on the nozzle for next summer...........just a heads up guys
