So I'm getting my turbokit installed sometime this / next week and I need to know how far / slow I should run it before I blow something... What I mean is that I am from CT, there is only one dyno I would rely on here and it's like 45 minutes away but really really pricey. Another one is in MA at UTI and my friend told me they would do it for cheap. Here's what's going into my car...

XS Engineering T3/T4 TurbochargerHKS Super Sequential Blow Off ValveTial 38mm WastegateHKS FMIC IntercoolerAll necessary Intercooler PipesXS Engineering Exhaust ManifoldExhaust FlangesDownpipeWalbro Fuel PumpBattery Relocation KitGauges: Boost, Air / Fuel Ratio, Oil Pressure370 Fuel InjectorsOil Feed LinesVacuum Hoses

I might have forgotten something...

But what I need to know is that I am going to be picking this car up and having to drive a minimum of 45 minutes to a dyno to get tuned. Do you think I will blow something with an untuned ECU?

yeahhh you need something to manage those injectors... atleast get a SFAC and set it approximately and get it tuned at the dyno.

could you be a bit more descriptive about the problems associated with MAF sensors than "nuts"?

Your MAF will be fine as long as your car is not producing more than 240 hp.. I think that is the limit of the MAF or around there.

For more HP people go with 300zx MAF
