Few questions for you:

Is your ecu stock or remapped/chipped?

Are you using the stock AFM or an uprated one (ie N60 or Z32)?

Did you check the codes on your ecu to see if it has trouble codes stored?

Are you sure you set your cam timing correctly when you installed your timing belt?

Did you make sure the ignition timing is set at 15* BTDC?

When your car got wired did you or whomever wire up the knock sensor?

Did you check your intercooler piping for leaks?

And lastly, are you sure your turbo is spinning freely?

For future reference, be very specific and descriptive about your dilemmas or your risk getting flamed and ignored.

is the smoke black or a blue-ish colored? if its black then check ur maf if its not letting u rev past 3k. if its a blue-ish color then ur burning oil and most likely a blown turbo. but if ur idle is screwy then its something else...

yes smoke is black and some time car takes off real good without any smoke but some time its smokes and doesent wanna go u know wut i mean? im pretty sure it wasnt turbo because i recently replace turbo inlet gasket and i check the turbo and it was good. I really think its MAF but i will talk to one of my friend and check the ECU and knock sensor and all that stuff thanks for all your info i really appreciate it!
