Looks stock, but it isn't.

hells yeah. i wouldn't run anything less than 91.

There is a newly released flash for the trd s/c. I made sure my tech used it. I'd heard about it on this forum. I've also been trying to research SL for any info on the bosch 110 bpv vrs. the stock 102. Some people say it adds power others don't. Everyone agrees that the 102 is cheap and poorly built so I think changing to the 110 will yield possitive results. I'm not going to use the forge 007 or the turbo x 25 cuz I don't want to have to change it everytime i go in for service. My dealership isn't really well informed on s/c or warranties at all. so i'm sure the 110 will pass for stock.

thanks to all that have helped. i'll post results soon.

Allright, I've solved the problem with the help of all who posted and some more researching on SL. I probly should have researched better before posting this problem, but I didn't know crap about BPVs until some people told me to check it out so

Problem #1: My tech installed the bosch 102 backward.
Problem #2: The bosch 102 is a peice of crap. It opens easily around 4-5psi and you will loose boost. You can tell when you compare the pressure that it takes to open the 102 against the 110. It's night a day.
Problem #3: As suggested earlier in this post there are some cons to having an automatic transmission. The ecu relinquishes power prior to a shifting point and there's nothing anyone can do about that.

Bottom line: GET RID OF THE STOCK BOSCH 102. If you want to maintain OEM apperance for warranties sake go with the bosch 110. If you don't care about that I'd recommend the Forge 007 based on what I've seen on this site. I guess it all depends on who your tech is and what kind of realasionship you have with toyota.

Big Ups to all who helped in this post
