I'm running a t-25, 370s, stock maf, stock de, jwt ecu, hotshot I/C. So my question is should I get boost, egt, fuel pressure; or boost, egt, oil pressure; or boost, fuel pressure, oil pressure? Since the jwt ecu runs rich is the egt necessary? TIA

Get a small fuel pressure gauge under the hood. Inside the car, get boost, oil pressure, and water temp. I dont really think you need the EGT gauge for just a t25, but thats just my opinion.

I just have fuel press, oil press, water temp, and boost.

If only going with 3 gauges... I'd go boost, oil and fuel pressure, in that order. If you end up with a 4 bar system, having a fuel pressure gauge which you can watch while driving is very helpful. I don't right now and I wish I did because I think my fuel pump has cut out a couple times and made the car run lean. Dunno though *** I can't watch the fuel pressure.

Thanks.
