I wouldn't have thought you would need a remap although it is advised to do it. You can probably run higher boost more safely with a front mount as it is allowing the air going into the engine to be a lot cooler. There is no increase in the amount of air going into the engine just a reduction in the temperature of the air.

 

so would you consider it to be a waste of money? as you state that its advised but not needed

 

get a remap done....cost wise there are many mappers out there and i would recommed Paul @ Zenperformance.

 

It depends. if you have the spare cash get it mapped as its one of the best mods you can do anyway but if you don't then i can't see it causing any problems. It would run better if you had it remapped but it comes down to wheather its worth it to you.

 

I have a 94wrx with the same sort of spec as yours with a small topmount had it mapped at scoobyclinic with a scoobyecu and got 295bhp. I fitted a FMIC with a custom induction, that I built into the wing and had it mapped again and got 330bhp/340lbft. So I recomend to get a remap as I got a huge jump, plus as it starts to get near winter you will start to hit fuel cut with overboost, thats why i had mine done.

 

what sort of price did it cost for you to get a re-map?

 

Definetly needs doing.

My boost peak raised by about .3 bar after taking a new age STI TMIC off and replacing with a hybrid.

The boost will need sorting, it will take more advance, and require more fuel.

 

thanks for all the advice will deffinetly contact powerstation thanks!!
