Hi guys I have an s14 with a redtop, currently everything is stock except for a t28 turbo upgrade.Here is what is happening. The car starts an idles great but once it goes around 2500 rpm it starts bogging and no power.
-Here is what I checked
Any boost leaks by spraying it with carb cleaner
ignition timing
fuel pressure and fuel pressure regulator
cleaned maf
-I replaced spark plugs

I have hooked up the nissan consult scanner and it says it is running lean. I dont know what to do and I am afraid of ruining my motor. This problem just started on its own. Any ideas?

BTW how can I check MAF??
