what turbo do you have? i have 35r run 30psi every day on pump gas sunoco 93octane and no problems.

 

Wrong forum man! If you're talking about the 8/9 in your info that is

 

26,000 miles and nothing but 21-25lbs of daily driving and many many days of 30lbs+ on C-16 . Get a good tune and you'll be just fine !

 

I didn't see that sig

 

no i got an evo x sss the thing is i have no tune and im running 25 psi with these mods on pump gas

 

I'm running 24 spiking at 26PSI and I have no problems! As others said, you won't have any problems unless your NOT tuned or happen to run less than the desired octane that your tuned for.

 

will it not run on 30 psi with pump gas? i was at awd motorsports by miami when i saw an evo x running 30 psi with the same mods as me but i was running 28 and now the car feels a bit funny like its not really pushing the way it was the night i boosted it and a week later after the races i droped it to 25 to be safe so how do i know i dont have a problem with the motor or what is the worst case senario

 

hummmmm i seee well im not tuned and iv been pushing the car consistantly for the past 4 months and i havent had anything bad happen iv recently been told i have flames come out the back like fireballs lol but thats it but hopefully i get tuned by the end of the month hopefuly nothing happens to my ride its my baby and all lol

 

o its a stock turbo keep in mind

 

Im spiking to 27psi then it tapers to 20 psi at 7k
runs great but im tooned for it!

 

i c well what COULD HAPPEN if i wasent tuned for it

 

you need a tune

 

Kaboom!

 

Whats the stock boost? 23Psi tapering to 15?
