Sounds like my van when I killed the new turbo, boosted well then a few weeks later dropped to 3500k then totally ran out of puff,

after faboka advise turbo maybe coming off next

On my pulsar if you disconnect the maf plug the engine won't rev past 3k it goes straight into limp mode it **** me up the first time it happened. How do you know it's not a fault with the ecu itself?

 

unplugged maf no difference as for ecu I don't but thought i'd have a code atleast also it was fine before engine build

Have you tried another working maf? I had an issue with the pulsar and tried all sorts, changed this and that to no avail put a different maf on and bingo she was right as rain. Just a thought cars can be right bitches.

It never threw up a fault code either which is why it took me a while to figure it out.

I've had same issues with MAPS, MAFS etc, all cheap parts from "fuel parts" hence why I now refuse to fit customer supplied parts unless from a recognisable brand and in working order. No codes flagged, just felt like someone had put a bit of rag in the intake. Also Steve basic but if running factory filter make sure air box is clear

all parts are genuine and its running a cone filter as I got another 1 now I might try maf but ones breaking either way so I got 1 really good 1

Don't bother with the MAF as it should (I would expect) be running MAP based so unplugging the MAF should make no difference.

How did you get on today?
