OK, HERE IS MY PROBLEM I RECENTLY BOUGHT THIS 92 TY WITH ALREADY ON IT AN ATR FPR,WALBRO 255,ULTIMATE CHIP,3 BAR,AND DYNOMAX SUPER TURBO. DID COMPLETE TUNE UP ON IT ATR PLUG WIRES,CONRAD C&R,PLUGS,OIL,BELT,PCV VALVES.THEN AFTER ALL THIS AT WOT THERE WAS A LITTLE CUT OUT AND THEN ONCE THERE WAS WHAT SOUNDED LIKE DETONATION.CHECK FOR VACUME LEAKS CHECK FUEL PRES. SET IT AT 50 PSI. THEN I FOUND THE PROBLEM A BLOWN INTAKE GASKET.JUST REPLACED THAT TODAY. WELL NOW EVEN WITH THE CHIP SET AT T115 AT WOT IT SEEMS TO CUT OUT BETWEEN 8 AND 12 POUNDS OF BOOST AND ITS EEMS REALLY SLOW WITH NO GOOD ACCELERATION AT ALL. MY FATHER SAYS IT MIGHT BE A CLOGGED CAT? I DON'T KNOW. IN A WEEK OR SO I MIGHT BE GETTING DATAMASTER BUT NEED TO BUY A LAPTOP FIRST.ANY HELP IS GREATLY APPRECIATED.

What spark plugs are you using and at what gap? The Datamaster is a fantastic idea. Your list of mods and tuneup stuff all looks good to me. When you say it cuts out, does it feel like hitting a rev-limiter where it's herky-jerky or does it just start to dog really bad?

IM USING AC DELCO GAPPED AT .35. ITS NOT LIKE HITTING A REV-LIMITER IT JUST CUTS OUT FOR LIKE A SPLIT SECOND THEN COMES BACK THEN CUTS OUT BUT THE CUTTING OUT REALLY HURTS THE ACCELERATION.

Are you reading boost on the stock boost gauge or on an aftermarket boost gauge? If it is the stock boost gauge, since you (apparently) have a 3-Bar Ultimate chip, that gauge will no longer be remotely close to accurate.

THE OWNER BEFORE ME INSTALLED IT AND HE SAID ITS A WALBRO BUT HE DOESN'T KNOW WHAT SIZE SO MAYBE HE MESSED UP THE INSTALL OR ITSTHE WRONG SIZE?

How about fuel pressure, is it maintaining under boost? Do you have an in-cab gauge?

I don't really know the answer, I'm just poking around for clues. The DataMaster will probably be the #1 teller.
