Since I installed my turbo its seems to pull hard until about 6k then it seems to hesitate and be all choppy like. What could be causing that and how can i fix it?

Either irratic timing, or lean fuel condition. My best guess is your lean.

I agree...my car did the same thing untuned, and after the crossover point I got a HUGE uncontrollable surge of power....after I got it tuned, its a smooth transistion, no hestitation

Hmm same thing will happen to me once in a while. but it's usually when it's heatsoaked.

thanks for the replys so theres no way to fix it until i get tuned

Get it tuned for sure. Like they said you are probably lean. Another thing to check that is real simple is your plugs and gap. When I boosted my car(only 5psi before newer 10lb pulley) it would start to cutout or jerk when I'd hit higher rpms. All I did was close the spark gap a tad.

yes get it tuned if you keep getting on it your engine WILL FAIL

it actually sounds more like it's runing too rich, If it was runing lean it would just not pull as hard. Hessitation is generally due to being too rich or poor spark. My guess is that you need a tune up (plugs, wires,cap,rotor) and/or lean it out a little. Do the tune now unless you just did one. I picked up 17whp by doing a basic tune up and another 10whp with a little fine tuning of the air/fuel ratio (leaning it out). Also if you were too lean, you would most likely have other symptoms like detonation.

how could i lean it out? Im trying to save up the money for my obd I ecu and the 500 to tune it but i cant not drive the car til then what should i do?

its like i hit a wall at vtec, because i have too much fuel(for sure)
just hadnt had time to tune it fully yet

just don't rev it past VTEC or set the point higher until you can get it tuned

...your avatar bothers me dude...that's really strange...hope thats a photo chop

one more chance

or maybe the turbo is too small and is pass its efficiency at 6000rpm? what turbo do u have? furthermore, you may have boosted it too high!

its a t3/t4e bossting 7psi

Whats your fuel set-up?
