hi there guys have been the proud owner of my new skoda Octavia vrs mk1 in black magic with a Perl in it. lowered on techknics coil overs. Eibach rear camber shims , Audi rs 4 wheels same color as car. Falken stretch tiers , performance exhaust , custom remapped ecu for track. toyo sport front mount , carbon air box with cold air feed. 4.8bar fuel regulator. ko3s hybrid turbo. fully forged polished and cleaned.

but need some help as am having a few issues with the car already. i brought the ecu of a friend of mine that took the ecu of a car that he had brought which had been mapped for track. but im thinking it might not be as it can rev round to like their is no tommorw but now it is getting more consistent as i can rev round in 3ed gear and at 4 grand it has a flat spot but now ever since this flat spot has occurred its revving round slower then usauall. so i plugged my mates diagnostics tool in and it is throwing up lamber and air flow but i did ant think that a lamber would do this. any ideas welcome as if i cant fix it the car will be going. also the other problem i have is i had a forged re-cert valve on it and it was taken of as it was very very sticky and i had a baileys dumb valve so i put the baileys dump valve on and my car is now making a very loud wining noise at me ermm so i dont no what better to use as the baileys did improve performance slightly.

so if anyone has any ideas to what the flat spot could be and what is restricting my performance much appreciated thanks roleyyyy
