Hi all.
Just wondered the best way to see when boost is comming in on MY03STI. I have pro sport gauges fitted and would like to know as I have Harvey headers to fit and buying a matched up pipe soon and wondering what difference this will make and HP increase to.
Thanks.

 

Best way to tell difference between hp and spool characteristics, imo, would be to go to a dyno and get a printout of before and after. Preferably using the same dyno too

 

You are having the map tweaked, I assume?

 

On the shelf £29.99+vat

 

I assumed he HAD one.......?

 

But not a TURBOSMART one

 

Yes, after fitment of new bits.
I have a set of three pro sport gauges fitted.
I just wonders how you tell/say when in the rev range you say when your on full boost, what gear you use and such.
