Can you check fuel pressure while under boost to make sure it is not dropping?

ok it seems that it is my stock wideband

took it to dyno and while dyno sniffer wideband was saying 12.0 kpro would say 13.8AF

what wideband that is not stock is recommended for kpro and how do you wire it? I would rather buy an aftermarket wideband than the stock one.

Thanks

Fuel pressure held til about 7500rpm then fell off but that was cause i put the stock pump back on instead of walbro and boosting 17lbs I believe. will put walbro back on and test again tomorrow

OK, good to see that you have narrowed down the problem.

The PLX or innovative widebands are both good, but they will not interface to the ECU so that you'd be in open loop the whole time.

so that means I have to tune partial throttle and non boost tables?
