ok, i am tight on money so i decided id post here before takin it 2 a mechanic. my newly purchased vlt (2 months ago) has an intermittant problem. i havent been able to connect any causes, it just seems 2 do it sometimes. it bogs down horribly in lower revs and runs like sh*t till i get it onto boost, then it runs fine. i have no clue what it could be as im still learning this stuff... mods are. T3/T04 turbo running rich 3 inch uni filter boost controller manual conversion plugs seem fine injector cleaner put thru it recently been runnin it on regular unleaded the guy before me ran 12 psi thru it. i turned this down to 9-10psi. during the 1st couple weeks, but it always ran better on 12 wen i occasionally tweaked it up. i put it on 12 today n it ran boggy as hell. it was running nice on 10 eirlier today. i have one idea, i think it is running 2 rich, because wne it is bogging down, it coughs up black smoke until it comes right. what if anything can i do to try 2 fix this? any help would be much appreciated!
