My car creeps in the cold. I've seen it go to 12psi. I always let off though and I'm very dilligent. I just hold half throttle after 9-10psi. Now that it's summer, and I have time to work on the car, what should I do?

Random side note question. 1300cc.com (which is a great reference site btw) says that a manual boost controller fires boost up real early. My car is generally done boosting by 3500-3800rpms. Is it worth it to get a MBC if I don't really plan to raise the boost?

 

Port the wastegate..

if i could vote for both, i would, but in the mean time port the wastegate, its near free.

 

You should follow the advice posted in literally hundreds of threads about boost creep, most of which you've probably read. Port the wastegate.

Any boost controller will increase the rate that boost increases, because they all work by delaying when the wastegate opens. Do not get a boost controller until you have proper control over your boost.

 

Port the Wastegate and buy a Walbrop 255lph fuel pump..
