Bipes pulls timing in relation to boost. More than likely it is pulling too much timing which would explain the lack of power and popping.

I don't know if I missed it, but do you have a fuel pressure gauge?

if you want just pay shipping and ill send you an AFM...i have 2 lying around

i've basically got it running fine now. its just at the stock greddy boost of about 5 psi i've tightened my wastegate so it hits 6 psi max. it doesn't sputter or pop or anything so all things are good. butttt i still would like to run more boost buttt again i need to sell my car soon... if there is a CHEAP way to run some more boost and make it a lil faster because i will be selling my car def. around spring so let me know some ideas. thanks

cheap and boost dont go well together

Don't change anything, just enjoy it. By spring, it should still be running and you can sell it as a running car instead of a project, like many do. Just my old man .02.

Or get a wideband. If we don't see your car for sale in spring, we will force you to get a wideband or we will ban you. Not really, I just made that part up.

well... he is running a turbo system + a dry nitrous shot. without engine management... so I imagine the engine won't last till spring if he hits the "go baby go" button on the shifter.

nice "gone in 60 sec" reference, but yea i doubt it'll last that long if does it hit
