Hmm, people run 9-10psi on a 3400 (185hp stock) and put down 358hp to the wheels... But that's with a manual trans.

They tune via OBDI with burning chips or an emulator. Using the stock ECM. One guy has megasquirt to run his turbo 3400. 3400 = LA1
The 3400 is a 3.4L aluminum head FWD pushrod motor. Lots of swaps into 2nd gen sunbird/cavalier's with 5spds, and some with turbos added.

I believe something is wrong there, you should be putting down a bit more.
"Hmm, people run 9-10psi on a 3400 (185hp stock) and put down 358hp to the wheels... But that's with a manual trans." That doesn't sound right either. You'd be 12 WHP shy of doubling your horsepower on much less than twice the amount of O2. I've seen stranger things happen but, thats not likley.

Yeah I don't know about that either. I have heard that a ported 3400 responds very very well to boost though.

Most stock 3400's when tuned propperly with OBD1 put down just shy of 200 WHP in a jbody 5 speed configuration. They do upgrade the intake and the exhaust downpipe which might be helping.
Midnight's 3400 wasn't stock, he had ported heads, turbo headers and some other random work.. but yes, 358 WHP. I dyno'd at 275 WHP w/o a turbo

I would almost agree with it being unbelievable, but we're talking Gen 3 stuff, the mpfi's would need more boost (not that much more though) to get those numbers.

And you're flirting with 12 second territory. Whens the 12 second slip coming btw SuperDave?
What power levels would you think is needed for a solid 12.9X run? You're using slicks right?

Yes, Slicks. the car weighs maybe 2700 lbs with me in it, so that + 275 WHP should equal high 12's on a perfect run. I'm still chirping the slicks going into 2nd gear.

Glad to see you are comfy with killing it where it can die with honor if need be
