BOOST PROBLEM WITH MODIFIED AIRBOX
Posted by LS [Email] (more from LS) on Tue, 26 Aug 2003 19:48:46

In an attempt to try and get the stock airbox on my 89 900 T to breath better, I drilled about 10 1/2 inch holes on the intercooler side of the filter housing. The problem is this:
While the throttle response is slightly better, the boost is not coming up as strong as before, and is also not holding like it did before the mod. Under full throttle, the boost doesnt even get near the red, and starts to bleed off at about 5000 RPM. The check engine light is also on, but I expected that. any ideas on whats happening? Is the AMM the root of it?
Thanks very much
