Right new problem holding back at 6000rpn

Right got misfire sorted now it holds back at 6000rpm like it over boosting it boost over a bar but it came from eclipse so thinking they might of wound the actuator up but wanna put my polar chip ecu in it any idears it's a 96 jdm by the way

A little more detail may be helpfull mate
Does it just stop at 6 thou revs and go no more in every gear
Does it just stop dead abruptly at 6k
Boost drops when you hit 6 k

Mine used to back off at 5k was down to a boost leak on mine
Mates facelift had similar problems i think and his was his intake pipe from eclipse was calapsing under boost but the andy f i think it was cut it down and its now fine

I think it's holding boost it's in every gear more noticeable in 5th it goes like a rocket then it just dies off I'll do a smoke test at work next week to check for leak but I had a leak on my McRae and this feels different but I have a front mount on this one got new coil packs yesterday grrrr I'm mangling my brain tryin to figure it out

I think ya just expecting to much from the car 6000rpm in 5th its call flat out,no more go go scoobys dont like flat out

Yeah agreed 5th is a utter useless gear lol would the front mount not be playing a part in this drew as a few have advised me against them even in my current build a large top mount is going to be better

Hmmm I can try an old top mount it's defo not all the car can give it max out at 120 mph my McRae goes off the clock after 160 this is on a run way of course

Ya sure bud ?.

160s a tall order for a somewhat standard td05 and injectors with a chip mate sumit not calibrated with them clocks bud lol. Be nice if the clocks are true. Mine where 5mph out at 125 and i assume the gap would be bigger higher up

Might have a vid on my fb clocks might be out but it shocks a few people

Could be a faulty speedo cable/bodged kpm to mph conversion.

Probably wrong but worth getting it checked out somehow

Told me it did 170 long before the chip was fitted. He even offered to prove it but I declined the kind offer lol..

Its a good chip as it was from mine but even in my car its ran 1.1 bar of boost with a td05 and hit 150 on clocks but mates showed 140 and that was flat out strangling the life out them with a uk box when i fitted my jdm box that dropped abit like lol

Nat it's coz ya a fanny it is a uk car but more to the point wot up with the new one the boost is holding over 1.2 bar sum thing not right there

Not certain mate you checked for fault codes ? Ide run the mcrea if its pulling them figure like tbh mate no dout tge new one will be slower lol

Right changed ecu for standard McRae one went class no problems so I put the polar chip ecu in fuckin even better goes like fook but I get a ting ting ring noise st really high revs full boost

Erm just to mention that ecus from a uk car you may need to swap some pinouts of sumit heard it needing to be done befor when putting jap ones in mate not certain on models ect
