I have a 89 turbo with custom ape chips bigger turbo, p&p o ringed head, adj.fpr, tial wastegate, hks evc and turbo timer,19 psi. boost etc... goes like stink but lately has taken to stalling at random. happened twice today while cruising along at about 40 mph. in 3rd, twice sunday, once at a light, once at about 40mph.Any insight into this little "idiosyncrasy" would be appreciated. I really wouldn't want this to happen in a high speed sweeper at the glen... those blue bushes are NOT soft...Thanks Dave

 

dme relay??? the a/c relay for late 944's is also a dme relay, try the switch and see if your a/c cuts out, and your stalling stops.
