Ktec Manifold fitted remap required ?

[silverclio4410]

I have a totally stock Clio 200 and just fitted a ktec manifold as stocker was blowing.
Car drives absolutely fine and dandy without issue.
My question is do I have to remap or will the air fuel ratios etc still be ok as it is with cat still in etc.

Is it safe ?

I'm genuinely surprised that the car drives fine. Mine had a totally noticeable flatspot around 3k rmp and even mapping didn't iron it out completely. Maybe there was a flatspot there to begin with due to the blowing manifold?

I would definitely map the car just to be on the safe side.

You'll be fine to run it without a map, but obviously will be affecting performance until done! Plenty of people run their cars decatted etc. without a map But as above, mine has a brutal flatspot just after a cat back (resonated too). Maybe due to the design of the manifold too. It is meant to be good

My car still has the main cat and that's how I wanna keep it.
The exhaust has had an affect positively and engine feels more responsive.
I definitely have no flat spot and the cost of a map and what you get in return really isn't worth it as it's n/a.
Will leave it as it is now.

You won't say that once you've mapped it. Makes a big difference, even if it doesn't seem like it when it comes to numbers.

If you don’t like mid range torque I’d leave it as is, look at any before or after map and there’s a massive difference, people look at bhp and think that’s it, you don’t drive normally at peak power, it’s there for about half a second per gear generally
