Default Loss of Boost?

I had a set of PRT's on my car and everything seemed fine.
I just put a Ti exhaust on and now my car seem to have lost quite a bit of power

It a P1SC running almost 600 hp and today I could not even trap higher than 115 at 11.40 I cut a 157 60 ft and top end seems to just fall out?????
last time out it ran a 10.70 at close to 127
I just picked up a set og GHL Mag+2 I hope that solves my issues

anyone have this same issues.
I think I might need a less restirctive exhaust set up??? any boosted guys running the Ti 's
I just cleaned my air cleaner and will install new plugs this week.
What would cause the boost to drop off?

any one help?

Vic

The Ti exhaust actually moves pretty good air even for 600rwhp centrifugal cars. I doubt this is killing you. But something is definitely up, I trapped 115 in a bolt on convertible C5 my first day ever at the strip.

I would look at other things first -- the tune, fueling, etc. When was the last time the car was on a dyno?

last year it was dyoned

we put the computer on it friday and drove it and everything seemed fine af reading was great
I just cleaned the air filter and will do the plugs this week.

I was only seeing 7 lbs of boost which is off from 10????? I just had the Belt and oil changed in the S/C head unit.

60 ft times are there (1.57)so If this does not help I will have to take it back and see what happened.

I have a set of GHL's coming so the combination of all these things I hope will solve my issues.

thanks guys

Vic

What do you mean you put the computer in it Friday? Was the car not dyno tuned?
