if i boot it in 1, 2, and 3rd, i have absolutly no problems, but in 4th and 5th it gets to around 3.5-4K and drops down about 600 revs or so then picks up again? turned the boost down to factory setting and was only happening in 5th.

car is MY97, fairly standard (appart zorst, pannel filter, dawes)

dont have a knocklink or afr

any ideas?

thanks,
Simon

 

tried an afr, running slightly rich on boost, but too rich


anyone?

Simon
