Boost doesn't seem right

I've been having the P0243 code. I never noticed a problem with the car until a week or so ago. Car seems sluggish. Also, the boost gauge only goes halfway when at WOT. I do notice it pegs out for a split second and then back down to halfway. I can also hear this action in the whine. I also don't leave anywhere near the amount of rubber I did before from a dead stop. lol
 


The rubber on the booster cap looks good. But, the hoses on it seem cracked. But I'm not seeing a leak. Should I start there and replace all those hoses since they are cracking.
 


GM Does offer that as a complete replacement for around $20.
Also, an alternative, but not as nice looking is making your own from vacuum hose and plastic fittings.
 
The gm prices went up, just after the first of the year i think.

I got the full line replacment for 35ish bucks, 2 weeks ago. That didnt include the brake boost lines.
 
Hmm ok. you guys know the part number to that kit? Also, I could probably just get a hose anywhere for the brake booster right?

It sounds like you got hosed then, because retail price is only $26.
Actually, the ones for the 04+ are cheaper, about $15 for them. If you wanna get one from the dealer, the number for the one that runs under the SC is 12580696.
 


checkers or now that its called oreilly has vacuum line like 35 cents a foot worked great on mine so far just when i did mine i took the car there so i can get all the right lines and lengths
