Bogging underload

[Legit6MT]

Whats up fellas, I just bought a 89 240sx w/ a sr20det blacktop. Im new to the 240's as well as turbo cars. I have a 02 VQ35 maxima w/ boltons and nitrous soon to be a high 11s car. I bought the 240 for a really cheap price and at first it seemed it was a bad maf, but it it was just the connectors werent good.

Now the car in neutral revs up preety good, bov goes off. However in gear, as soon as it starts to build boost the car bogs hard..

spark plugs will be changed tomm as well as a boost leak test soon..

any suggestions are welcome..

The Bov goes off in neutral?Chances are the Bov isnt tight enough and under load as soon as the car starts to make any boost its creating a massive vac leak.

Tighten your bov and see what happens.Its a simple and free test, if that solves it then rep Nali, else report back and ill keep thinking.
