Ok cool. Thanks! I will buy an MBC tomorrow.

Your n75 might be bad, but it could be something else. If you dont have any fault codes, buy a volt meter and test your n75. Search for what the correct reading should be. Dont just start guessing and replacing parts at random. If you do get a mbc, dont be an idiot and crank it up without proper tuning. Your ecu wont adapt for the added boost like 00+ engines do with the diode mod/mbc.

OK, I will do that. And also if it is not the N75, what else could it be?

If you remove the N75 and check the resistance between the two pins, it should be 25-35 ohms. Thats the only test I could find that doesn't require some special equipment other than a multimeter.

 

OK, so I am still at a loss here. I need to get this fixed and I can't figure out what is going on. No codes and the N75 seems to be bad. My boost is REALLY inconsistent now. Like i can hit the gas and keep my RPMs in the same area holding xPSI and then randomly my boost will just jump up to a much higher amount without me actually pressing the gas peddle harder. It is almost becoming a special skill to drive it with out it jerking around a bunch. If it's not the N75 what else could it be?

Do you own a multimeter/voltmeter? The are pretty cheap, it would be a good investment.

 

I am going to pick one of those up here tonight or tomorrow.

Im surprised you dont have any fault codes though. I bet its the n75, but it might not be.. Youd probably be kind of upset if you spent $70+ on a new one and it didnt fix the problem though.

 

If I just got an MBC and bypassed the N75 would that work?

Josh

 

OK, so i just tested the N75 with the voltmeter and I got a few different readings. At one point it was jumping around from 55-120 and then it leveled out at 31.5. I am so confused. I also rented a code scanner and have scanned it multiple times and I still do not get any codes. Any other ideas???
