Right basicly ive been having a few problems with my emissions on my fiesta rs1800

see here: https://passionford.com/forum/technical-help-q-and-a/242318-fiesta-rs1800-zetec-trouble-smoking.html

it was running around 14.** on the emmisions test with the standerd airbox and 1.8 maf but with the 2.0 tb

i changed the maf to the 2.0 mondeo one and it dropped the emmisions to 8.**

Since then ive fitted the 1.8 lamba which made it a bit better but since then i havnt had a emissions retest to see how much crap she is kicking out.

i also refitted my 1.8 tb but this made my car rev to around 3000 at idle!

I have booked a mobile diagnostics van to come to my house tommorow to plug my car in to see what he can do.

But ive been thinking will it be best just to give my car a total remap as it is so it runs perfect how it is as it only runs funny through the revs while driving like it struggles to pull and idles fine now.

Im just thinking whats the best thing to do as the car works, its just not all working together. Im begining to think i remap might be best? whats your ideas on this?
