I have a 88 T2 that I just recently rebult a removed the rets nest/emissions. I am getting a dffcult to diagnose problem with the car. Under heavy acceleration t has a hesitation at 5200rpm, the at 6,200 then 7,200. The injectors were cleaned at rc engneering during rebuild. After the rebilud a down pipie & test pipe were added, as well as a boost controller. The hesistation was there before the rebuild or any of these after market parts were added. I have a feeling it may be the tps. I dont think the map sensor is bad because besides that the car runs well.

If anybody can help my It ould be much apreciated.

 

check for vacuum leaks, boost leaks (intercooler and piping), check the tps for dead spots. do you have a fuel controler? you may be hitting fuel cut.

 

fuel pressure ok? Could be a tired pump.
