Hesitation?

[pgiller]

I have a 89 mk111 and I just put a aftermarket ic and hardpipes on. Well after I got them put on i took it for a test run. It hesitates pretty bad in 1-3 gear only at first, after i get the rpm's up it runs good. Oh and it back fired a couple of times. Any and all help will be appreciated.

Could it b anything else?

it also cuts out if give it to much gas, the gas pedal is really stiff. And if i dont give it enough gas then it spudders and the turbo spools out? What the hell is going on? It has a sweet spot in the middle but i know its not supposed to run like this. It also uses alot of gas

check for vacuum leaks, check resistance on your afm and tps, and check your spark plugs.

Is it throwing any codes that need to be fixed?

it should be a boost leak
