I put some 44lb bosch injectors and was waiting for the tuner..... long story short he didnt show up.... so my truck ran like crap, naturally. I bought HP Tuners and Im currently learning it. The big problem is as soon as I put the injectors my boost couldnt get up past 2-2.5psi. Im getting the fueling worked out but I still cant get the boost up past 2-2.5psi. Am I doing something wrong or does the more fuel thing mean less boost?

 

How about some info on your complete setup?

 

I dont know how injectors could effect boost unless its running so rich it wont rev. Yeah some more info will definately help

 

I no that bigger injectors will def rob the hell out of your low end power, if not tuned, but dunno bout why it isn't boosting.. Some info would help..

I put the whipple setup. I couldnt get a tune right away so I put the craptronics at first. I put a boost and AFR gauge and they said 6lb and lean. I bought some injectors and waited till I could put a tune to install. Well I found a local tuner that sounded to good to be true (he was). So he tells me hes gonna come to me and tune my truck. Also to install my injectors so he dont have to come back. So one day I pull all the craptronics and install my injectors. He doesnt show up!!!!!!...... So my truck ran like crap obviously. So it drove me to go buy a tuner since I was looking into getting into tuning anyways. So I started tuning from there.

 

so your on a stokc tune right now. I would not got WOT with that thing. Your timing table need to be toned down a lot and it needs to be richended up a bit.

 

Its a 2bar OS but I dont know what else I need to tune. Ive got the right amount of fuel going to the injectors.

 

Did u use a wideband for the 2bar VE

 

No I didnt, I tweaked off the original

 

After 105 KPA your VE dosent look right,not enough fuel,get a wideband.Take it easy.
Even your PE needs help.
