Hey peeps, im new to the mitsu world

Ill hopfully be takeing home a 99 GST (auto) on tuesday. cant get financed untill after the holiday.

Im getting it for way under book value.

Ok its pretty much stock

New head and gaskets
ebay 2.5' hard pipes with the factory turbo and smic

My ? is THIS

I had a vac leak and replaced all the vac lines and cuplers. car wouldnt go past 5lbs (this was before i fixed the vac leaks)

Now the car gets up to 10lbs of boost and stutters real bad and wont boost anymore. my boost gauge at idle reads -10 if i rev it to 3000 and get off the gas, it will read - 15 to -20 and hold it. this seems kinda low.

How do i fix the stutter problem, i will be changeing the plugs and wires cause i have a light miss fire.

If this helps other mods are apexi turbo back.

iv heard these are known for turbo problems

send me a pm if you can help

Thanks, hopefully be happy with my first mitsu
