blast first proper drive since fitting chip
EEEEEEEEEEEEEE ITS A HARD ONE THIS
TAKE THE CHIP

 

check your dump valve isnt letting by if you have one mine was cuasing all sorsts of crap under boost

 

standard re circ valve been out since and its been fine done 50 miles and havnt happened since

 

I assume you've had a proper remap after fitting your "chip"?

What "chip" is it btw?

Here's a rule of thumb for Scoob ownership: play with it without knowing what you are at, pay for it later!

And an engine rebuild to standard is £2000

 

Its a my95 standard ecu cannot be remapped its a polar perf chip its been running fine since just been out lookin under bonnet and found neg on batt to be loose perphaps thats my fault tightened connections took it out the fault hasnt come back

 

OK, best of luck with it, and the car.
