hi guys, i got a problem for ya. I bought a 180sx 93 with the sr20det engine in it, like a few weeks ago. Now the chick i bought it from said when she bought the car, her parents had a drive and pretty much said its too powerfull, you'll kill yourself. So they took it to the mechanic and he 'did something' and after the power was decreases. Not sure if it was acceleration or top speed, just the power dropped. The only hint was she said 'i think they changed something on the injectors/throttle body side of the engine. Any ideas? Can u lower the boost? the throttle body opens completely and the TPS is correct. Any thoughts would be great and i am more than happy to run any tests on it. cheers all..
