New 04 WRX with mods help!
Hey guys I'm new to the forums and the subaru scene and also to force induction engines. I bought a 2004 WRX sedan with some mods and it is FAST! I'm worried about if it has a tune or not because I got it from the dealer and no way of contacting the previous owner that i know of. Here are the mods:
CAI with a Injen filter in the fender well
HUGE Downpipe like 4" and 3" cat-back exhaust(there is a cat)
Boost guage (working)
Innovate Motorsport LC-1 with A/F guage (works but needs a new O2 sensor according to the error code it shows)
Now the car is damn fast it seems to go 0-60 in about 5 seconds and it will run about 12psi max in 2nd gear, about 14psi in 3rd gear, and i got it to almost 16psi in 4th gear at like 5k rpm but thats when I slowed down because i was going about 110 up a hill. The weather here in SC is about 85-90 degrees F.
It has a CEL and the only code it shows is EVAP system leak detected.
It seems to run great the only thing i notice is sometimes the idle searches a bit between 500-600rpm sometimes going low to where if it was much lower it would stall, it only does this sometimes and only when it has already warmed up.
What im wondering is if it wasnt tuned would it throw more codes with these mods?
I'm just worried that without a tune it could damage my engine.
I have driven it over 3000 miles since i got it in about 2 weeks. (mainly because of the road trips I absolutely had to make and this is my only car)
IS there any way to tell for sure without spending money on $100 cables. Is there any CHEAP method of data logging where i could post results for some of you guys to look at? or any other way to tell for sure because I'm almost scared to drive it hard anymore until i know for sure... Thanks for any help!
