New Turbo Low Power

[TurboDSM86]

after all the fun and everything wore off w/my 16g install it seems my car doesnt have that much power to it anymore. i am only running 10 psi w/stock fuel still..(have injectors/pump/safc but not in yet). i have no data logger although i found one on dsmtrader. it just doesnt seem to have a big pull to it once the turbo spools. it will hit full boost by 3200ish or so but really doesnt have a pull to 4500..its impossible to try to launch b/c you cant get going. im not sure what to do w/o a logger or anyway to monitor it. maybe the ecu is pulling timing by a lot. i dont know where to start. there isnt any boost leaks or anything of that sort. im assuming im probably running lean somewhat so i have been staying out of boost. the turbo seems to lose a lot between shifts and im a pretty quick shifter. im confused and not liking my car lately due to it breaking so much... :thumbdown:

That 16g won't feel like anything with only 10 psi. I turned mines down from 17 to 14 and it felt like I turned it off. Have someone watch you run the car through at least 3 gear changes to see if you blow out black smoke during shifts. If so then start increasing boost 1 psi at a time until the smoke becomes faint. If it doesn't smoke at all then you could be too lean so turn it back down a tad. Try this until you get a logger and see how it feels.
