Unhooked top air pump connector

I just unhooked the connector (the one ontop of my airpump) i was just wondering if this is what the car would be like when the actual unit is out.

Things i noticed while driving,
Could smell a mild burning.. think this was the cat
I could actually hear my turbo spool more clearly
I did notice my idle was a bit sloppy
and when my car started up it stunk like hell lol probobly the extra fuel or something ?

ANyways was just wondering if unhooking the black connector at the top and driving would be a good simulation as to waht to expect if the whole unit was removed.

Also i still had all the hoses hooked up... would this change anything once i remove all of the hoses?

yes....most say no difference in performance, however ive noticed the car revv's faster...almost like a lightened flywheel affect

if you do run without the airpump, you have to set the idle up via the throttle body screw located behind the plastic elbow...u must remove the plastic elbow to see the large screw in the bottom right corner of the TB...set your idle up to at least 1250rpms and you are good to go

Sweet any idea what that burning smell is ?
I really wanna get a mid pipe wat effect does the midpipe have in terms of performance?

a hell of alot....30rwhp or more....enough that when you put in a midpipe alone on the stock boost solenoid system the car will instantly spike to 17psi and will creep up high in the rpms on boost

if you go to a midpipe make sure you either pull the boost solenoid plugs and run WG spring pressure 7psi IMHO ull end up with 8psi and this is faster than the stock 10 with a midpipe

buy a boost controller as the stock solenoids simply cant react fast enough to the new spool

and....when you get a chance port the wastegate..until then buy and exhaust flange for 2.5inch exhaust and stick it btw your midpipe and catback

So there is no way to control the boost just by watching the boost guage and throttling accordingly?

not effectively or safely enough. If you are going at WOT, and in a split second, you can spike to 17psi and that is all it takes for your motor to go bye bye.

I have a 3" DP, gutted stock cat, hks carb ti and a stock airbox. I have the airpump disconnected and don't have the ACV either. I am thinking of getting a hi-flow cat to reduce the smell and the noise as well. I have heard of people running a hi flow cat without the airpump and not having a problem and I have heard of them melting....I haven't had any experience with either...
