I bought the prosport egt, oil pressure and boost gauge for my evo and they worked great. The boost guage was dead nuts on, i was suppose to be boosting at around 20.5 and thats what the guage showed. On my buddies speed 3 i got him to get a prosport and it is dead nuts on his too, he peaks to 16psi and tapers down but like i said its as close as you can get and for the low price you cant go wrong. Sorry but defi is overrated, get prosport and use the rest of the money that would have been for those expensive defi's and by some more toys.

 

I agree with you gotboost. How long have you had the prosport? any pics of your dash. I just want to find out hows the quality of this gauges coz i dont want to keep on buying ones if they fail.

 

Get a wideband. if you dont youll wish you did at some point. It is more important than a EGT or oil pressure.

Here is my dash


AEM Truboost and AEM UEGO wideband. They are more expensive but they have interchangable face plates to black or white and same with the ring border. on top of that the boost gauge reads in digital and also works as an electric boost controller too so I can adjust boost from my guage

 

what the wideband? is it easy to install? those are nice gauges by the way. When they light up, what color is it?

 

DEFI makes an Oil Pressure/Oil temp/coolant temp all in one digital display that is amazing.

 

It reads air fuel ratio in real time digital. it is the only way to truly tune a car. it is easy to install as long as your exhaust has an extra o2 bung otherwise you need a welder too
