im on stock fuel except for walhbro 255. on a single gt 40 setup. heres my ?, when im boosting 11psi or 14psi, my afr's dont change much @10.3. is this normal, could the stock 370cc supply enough fuel for 14lbs on a gt40? i dont think so, but was hoping for some input. thanks.
afr?s

I wouldn't even play around with turning up the boost on a single turbo with stock injectors. You're playing with fire, IMO. Your boost could jump up higher than you think you set it on a cold night. Your boost controller might act up and spike your boost or the WG hose might pop off and you won't have enough headroom with 370s. Hell, that happened to me with stock twins and I fried a couple pistons.
Did you ever fix that boost leak problem you were having that caused you not to hit full boost until redline?? Didn't you mention you only dyno'd like 235hp or something like that? Did you ever fix whatever it was causing that low number?
If I were you, I would leave the boost alone until you get some adequate injectors and fix your other issues in the system. Just unhook the boost controller so you don't get tempted. That's what I did.
yeah, i turned my boost controller off. something isnt right though. im running 11psi with it turned off. it pulls good nothing out of the ordinary, nice and smooth. checking things over more thoroughly now. found a ground with the funny black box attached to the prong near the driver side engine compartment fuse box. my battery light came on and voltage was dropping, checked my alternator wire and it fell right off the connector. but i know i cant be anywhere near 15lbs with stock injectors on a single and still be running rich. i checked the injectors just to make sure they were stock, yellow tops. damn this is ticking me off. i got a set of 440cc, usdm 550cc, and a fuel controller, but dont see the point of them being put on if the car isnt boosting right yet. i dont mind taking it to someone, but im unable to trust anyone with it. nowhere reputable to take it. yeah, i could have it dynoed but they wont be able to troubleshoot and fix my problems. they dynoed it with all these problems. oh, i did fix my boost leaks. gonna check my compression and timing when i get a chance, dont see them being off, my car runs really well. it runs stoich under idle and part throttle. hey thanks onejoezee, sorry had to vent though. could u point me in the rite direction? oh gonna check my map sensor also, the engine was hopped up over in japan, who knows what they could of done to it.
