lack of power and early rev limiter

[m22pre 0]

Hi , i was heading to work this morning and fancied a little blip as the roads were empty. The car seemed sluggish but then seemed to pick up alrite again after 3000 rpm. The car has now developed a new rev limiter at 5700 rpm. can anyone help or suggest what i can look at to try and sort this problem?

car spec

superchipped ecu

Full exhaust system (not decatted)

FSA Fuel pressure reg

Gasflowed throttle body

plugged it in m8, only came up with lambda fault , got a new maf from gsf this afternoon seems to be alot better but still limits at 6200-6400 under load

I thought that 6200 was the soft limiter anyway?

It is!

soft limiter???

[VR6Pete 1,455]

yep, it soft limits at 6200, and the limiter is 6400 mate. its normal unless you tweak the map to raise the limiter

gettin a bit worried as my m8s vts came past me last nite (not my proudest moment) surely that cant be right ????

that doesnt sound right to me. i got passed just about by my m8s clio 182 but as these have more power and are lighter suppose thats about right
