i recently upgraded my turbo from stock to vf34. mods are as follows with 02 wrx engine:

intake
greddy fmic
vf 34 turbo
sti injectors
walbro fuel pump
colder plugs
catless turboback exhaust
catless uppipe

heres the question. can i run the stage 4 download map from turboxs on my car if i use nos's octane booster? it claims to boost up to 7 points. im almost done with my car. probably today.

 

Have you tried contacting TurboXS? They would probably know more about that than anyone else... Just my $0.02

 

Don't waste your money on the Octane booster. Do a search for Xylene.

When octane booster says "7 points", that means it takes your 92 octane up to 92.7. Use 1 gallon of Xylene to a half tank of 92 octane gas, and you'll get 95 octane. Xylene is 117 octane. Toluene is another additive used by a lot of people. I belive it is 114 octane.

 

yeah "octane boosters" don't work like a lot of people state they do. in reality they will up the octane by 1 if you are lucky. they have a better effect on lower octane gas (i.e. 87 octane) than on 91 or higher.

so i am going to say know you can not run a map tuned for higher octane gas using 91 octane with some octane booster added

 

thanx a lot for the info guys. i was gonna do an all out run thinking that it'll be ok if u guys didn't tell me. i guess i should think about paying and getting my car tuned since i don't know how to do it myself. but just out of curiousity.. does ne1 have a map for the utec with my setup running on 91 pump gas?

greddy intake
greddy fmic
vf34
walbro fuel pump
1 step colder plugs
sti injectors
m2 catless uppipe
helix catless downpipe
hks catless exhaust

maybe save myself from spending 600 dollars on tuning?

 

mmboost runs a 91 octane map i believe you may pm him for advice

 

paying for tuning is never a waste of money. even if you do get a map from someone i would still go do a few dyno pulls to make sure everything looks alright and is running well.

mmboost has a similar setup minus the fmic and i am not sure if he has gotten his map to run quite right yet. (i could be mistaken)

you might want to pm porkchop, he has a very similar setup and has been running utec for a while now and the car runs well.

 

thanx a lot for the heads up.

 

last question guys.. can i drive my car about 10 miles on stock map?? thats how far it is to easy street motorsports. thats the tuning place.
oh one more thing.. is easy street good or better than xs engineering at tuning utec??

 

The stock map should prevent overboost unless you have a mbc. If your really worried just keep the gas to a min and watch your boost levels.
