Hay you guy's ,i just finished seting up a new RaceTech piro &Boost Gauge.The piro read 680*c on it's test run ??,the 3 Ltr was running just fine as allway's . I think this temp read must be incorect as it seem's hi to me .What temp should i be expecting at max rev's ? About 500 or so ? The probe is just south of the turbo where the 2 3/4 ex Stym had a plug & pre setup for a temp probe all ready in the pipe so it should be in the right spot.If that was the right temp it would have a melt down a long time ago,My be the gauge is faulty ?? .What do you guy's think.
