Flat Spot In 33

[Gregors]

Hey all,

Being my first import, there are things that I'm still unclear about, and I'm just looking to bounce some ideas off all y'all.

I have recently got a new dump/exhaust installed, and it's changed the power delivery. Before I had it installed, it seemed to have smooth delivery until redline, and when I had the boost controller on, it would pull like buggery till bout 5500RPM, and then sort of tapered off, not a complete died-in-the-arse situation, but just pulled less hard.

Now with this new free flowing exhaust, it seems to be doing similar thing, even with the boost controller off. Am I right in thinking that it's just my widdle stock turbo running out of puff?

Its the stock ECU, get a tune

So it's cutting fuel or what?

More like running with too much fuel, its running too rich. Get a SAFC Neo or some piggy back with a tune. It will be fine after that.

That would explain the flames I have been shooting
