Hope you swap out the stock pump as well, they are very small not sure about the flow we use walbro
pumps .

Yep. I'm running a Supra turbo pump as well as the 12v fuel computer bypass.

Is it possible that the ecu detects and corrects a lean condition before the dyno ever reads a lean condition?

easy way to find out if ecu is pulling timming because of knock level.. try putting somer of the race gas and boost it at same levels of boost and so see what it will do... same boost but higher octane will determine if its caused by knock or not..
I hope it helps


P.S good looking car and nice number.. keep it up

Thanks. I'll try this tomorrow!

Also, the vacuum line setup to the stock FPR is normal EXCEPT that I have a double-tee installed in the line that actually runs to the FPR. One part of the tee goes to the heater VSV and the other to the charcoal canister.

Do you think that this could have some affect on my fuel Pressure on the top end? I've read that nothing should be tee'd into the FPR vacuum line.
