this problem is killin me still
 

:KANE: alrighty i post about 3 weeks ago about high end hesitation on my 95 gst i checked for boost leaks but im getting full psi of boost i changed plugs and wires and the recoil was changed when i bought it i had to change my ecu when my o2 scensor cord got messed up and fried my ecu and now it can get up to 4 and then it hesitats i also changed the fuel filter could it be a bad ecu i got from the junk yard?

mods done .14b turbo and just a hks intake filter and boost gage and a/f gauge

fuel pump?

Re: this problem is killin me still
 

Is it tuned? The larger turbo and higher boost will require more fuel to run right.

Also, where the hell is the recoil on a DSM? :lol:

:rollinglaugh: ^Is it a pull start haha. But on a serious note Fuel management is a must.

haha woops i was thinking about this lil go ped but yea ill try the fuel pump..

Re: this problem is killin me still
 

How much boost are you running and is it on the stock fuel system? If it's knocking up high that can cause pretty bad hesitation.

A logger does wonders for diagnosis.

Crack open your ecu and see if the caps leaked on the board, that can cause some crazy problems. Check your knock sensor. Check and see if your Mas plug is loose or if there is corrosion on the pins, test your fuel pump relay if the terminals are corroded it may work at less rpm but as it goes up it may not be getting the voltage/amperage it needs.

It does sound kinda like a boost leak problem, what did you test your system to?
