Depends where at in Southern Cali you at. In the San Diego area there is Donnie from DRW Transmissions, up in the LA area there is Richie from GN1 Performance, and somewhere in between (area wise) in Lake forest there is Turbo Lou.... but to get a better answer, you might wanna post in the Southwest Section, thats where they all hide at!

BLM's are too high. You have a vacuum leak. I would start there, although when I had a vacuum leak my car still ran good. Maybe your MAF is going bad? Or your fuel pump is going bad? To check fuel pressure, you would need a fuel pressure gauge on a long hose so you can attach it to the fuel rail and tape the gauge to the windshield. If pressure doesn't rise 1 psi per pound of boost, your pump is going out and you can lean out and damage the motor or blow a head gasket. You might have heard all of this before but it could get costly to pay someone to check the "simple" stuff.

Some have said to tap on it with a hammer (not too hard) and if the car sputters (or somthing) then the MAF is bad. As for me, I noticed that the car didn't start as quickly as it had. Then a couple days later, it was bucking and nearly stalling on the highway. When I unplugged the MAF the car smoothed out. Doesn't sound like this is really your problem though. Sounds more like the fuel pump to me.

Great! The money you saved on the mechanic can be spent on the new MAF/Translator!

Well, the popular one was the Walbro, sold by Full Throttle (same place you ordered your translator/MAF from). Some were failing prematurely and they kind of got a bad rep from that. The problem is supposed to have been taken care of by issueing refunds to anyone who got a bad one (I was one of those people). Do a search on fuel pump and you will find more info. I think Jegs/Summit sells the Holly. Maybe Mike at Full throttle will give you a deal if you buy the pump, hot wire, and a chip in addition to the MAF/Translator.
