Hi guys, i have checked my vaccumes all fine, i have check the leaks there are no leaks, i have checked the turbo controls from primary and secondary and every thing seems to be working perfectly fine, the problem arises when i floor my car as soon as i do that lets say in 1st gear my boost will kick in but then the car would start to hesitate very badly at around 2500 rpm if i let go of the pedal and lets say it pressed 25% of the way the car would go but not hesiatate but as soon as i would floor more than that the car would hesitate and then at around 4500 mark all boost is gone and the rpm would go up very slowly as if there was no compression in the engine (i have cheked the compression also) and as soon as i let go the padel completly the car would give loud bangs from the exhaust and when the car hesitates there is a lot of fuel smell in the car, i have no clue what is the problem with the car if any one ca please help me out i am really confused.

The spark plugs were brown and crusty.



Replaced them.
