What would cause low pressure while brake-boosting?
I'm close to having my car back to where I think it should be as far as power. Data from the track last night shows I'm only off by a couple tenths. The only thing I still notice is that I don't get near the amount of boost I should while brake-boosting. Boost comes on strong and hard after the first 100-200 ft, but prior to that the car feels like it's gagging a bit. I've done this technique a lot with this car in the past and know that the boost used to build much stronger. Here are the things I've checked already: tightened hose clamps, new air filter, cleaned MAFs, new boost sensor. Any other ideas of what I should be looking for? Thanks!

997.1 turbos have always been able to brake boost, nothing required from the GIAC tune. I've had the tune for a couple years and have never had problems brake boosting until recently. I can't seem to build enough boost prior to launch.

Ok so you must have a tip right ? because i'm positive on a 6sp it's not an option it has to be tuned in & Giac doesn't offer it but Proto does & also Cobb & maybe some others,maybe someone else can chime in here.I know when i had my Proto tune i could do it & also now on my Cobb & it def gives you a sling shot effect when done on a roll.
