So I got all my parts ordered for my turbo kit. t3t4/fmi/chipped ecu/ boost gauge/bc/wg/440cc/155walbro...pretty much everything. Do I need a fuel pressure regulator or a fuel gauge. About %50 of the setups i see have a aem fpr or a cheap ebay one with a gauge. I am only doin 10 psi max. I just didnt think with a chip tuned ecu I would need one. Also how important is it to have oil pressure/temp gauges, egt gauge and water temp gauge? Are they critical part of boosting a daily driver? whats wrong with the stock temp gauge?

Thanks

 

FPR aren't needed for any street car or most medium duty drag cars, at all. 255HP will overpower a small exit OEM FPR, but I've broken 640 off of a large exit and it would have been higher but wheelspin is a bitch on dyno readings.

Your factory gauges, plus oil pressure and tach if you don't have a factory one, are all you really need. A fuel pressure gauge can be handy for troubleshooting, but it's far far less important than an oil pressure gauge.
