exhaust/boostcreep question

[jaredgsx]

this saturday is going to be my first day at a dragstrip...i want to get atleast 8.5

I have a 14b turbo, 15psi of boost, fmic, mbc, 2g manifold, dejon upper ic, prothane motor mounts, its a jdm engine, and i have the back seats, spare donut, carpets, and panles taken out of the back.

I raced it the other night down the strip but they did not have a way to clock me, my dad is friends with the owner he lets me run sometimes....but with out knowing what i will do then i am just as bad off. the guy who had the car before me ran a 8.9 with just the jdm engine and 13 psi of boost.

Now my exhaust/ boost leak question. I was thinking a way to ensure that i could get some more power for the my first time to the track without having to spend a few hundread would be to just un-bolt my exhaust from the cat back ( at the track only) i know that would free up some ponies but i am scared off boost creep. If i do take off the exhaust, and from what i have been told, it will boost leak, since i am running 15psi, should i just turn it down to about 12 and let it creep up? would that be a way to manage it?

that would be a quick short term fix, but i would just say run it with your full exhaust and set your psi around 15-17. this way you'll know what YOU (not someone else) will do with your car with that setup and once you start doing upgrades you wont have to take your exhaust off every time you want to go to track. Also it might just be me but i'd rather say my car did a fast pass in the 1/4 or 1/8 as it sits rather than saying "ya it ran a ??.?? in the 1/8 or 1/4 but i didnt have my exhaust on and didnt have this and added that"
Hope that helped a little

yeah, i was just wondering if it would actually help to remove the exhaust or would it not be worth the trouble ( ie, the work, boost creep, yadda yadda yadda)
