Hello everyone this is my first post. I have a 04 Rex, here are my mods then my question.
Turboxs stealth back
dc flex up pipe
all silicone hoses
all marine bolt type hose-clamps
greddy steel mesh-cone air filter
perrin 1lb crank pully
cobb tuneing reflash
short throw shifter
i have two questions one what stage am i at?
and two when i did all these mods running 92+ everytime i let off the gas it soundes like im popping pop corn and back fires loud .
My dad has worked for Cumming's engines for around 40 years. He told me to stop useing 92+ gas and try one tank of 87. So i did it runs like a different car no back fire and it runs great and im getting better performance and gas mileage this goes against everything i have read or know to be true. Will it hurt the car to run 87 in it??
