This car has a 190 in it now and i started street tuning it and cannot get it to richen up at the top end. Sometimes just driving it it will completely lean out and shut off were you can barely keep it running… and then it’ll just come back to life. Almost like its sucking the fuelrail dry… I dont know though. It figures I cant get crome to connect to the datalogger so I have no idea whats going on plus the dudes tach is ghey’d up b/c of white face gauges… UGH\* > > I think im going to toss a 255hp in it and hope it fixes the problem. The only thing I havent done is build a completely new map from scratch, which I know the kid isnt going to pay me the time to do. freakin running a business swallows elephant cawk. So how are you tuning the car with no datalogger, watching the wideband and guestimating what cells to change? When I replaced the engine in my teg a couple washers got swapped in the fuel rail and it was sucking the rail dry basically doing exactly what you describe. I threw a gage on the fuel filter and it was showing insane fuel pressure all the time. Basically I had pinched my fuel line off supplying the rail so everything before the pinch was high pressure, everything after would be stock until it couldn’t keep up and would drop off drastically. Also as stated above a leak at the pump will make it suck. I have that gage if you need it give me a ring and I’ll pull it off. My car hasn’t gotten driven much lately --- _[View the full topic](https://forums.speedlife.net/t/is-a-190-walbro-enough-for/199124)._
