i just chipped my p06 for the uberchip and it idles way better than the vafc hack. The problem is that when i gas a little bit the vacuum goes from -18 to -10 and starts to hesisitate. Little gas and the vacuum goes up like im in full throttle. My question is what is the problem? you think a restrictive exhaust could cause hesistating? thanks guys

 

make sure your injectors are scaled correctly... sounds strange-possibly tip in / tps related. you dont have wideband access do you?

no i dont have access to a wideband. i am actually running your bin, dyno8. Tps related? what could i do? oh yea have stock exhaust on and could a small exhaust cause hesisitation?

 

that is strange, i had no such problems with my bin. I have no idea the stock exhuast could be richening it up, that bin was for 3" open downpipe on 91.

 

im running 2.5 dp with a stock exhaust and 93 gas. YOu think im really rich? maybe i should try open dp to see how it runs.

 

to be honest im not sure. Is it when you give it gas from not having gas it hesitates? That sounds tip in related

 

People with the OBD-0 chipped ecu's are having hesitations at 10 and 0 I believe. So if you guys figure out the solution let us know!
