Looking at installing a PW surge tank. Has anyone installed one and driven with it without a re-tune? How was it?

Without retune it will run rich...

I installed a twin pump surge on the weekend, definitely running rich,but better rich than lean. Re-tune when all the other mods are done, but definitely a re-tune

Yeah I'll be getting it retuned but not for at least a month. Just so I know if I can start using it now or install it later.

you can start using it now, not going to cause any harm, but will simply run rich, potentially if rich enough it will foul plugs, but I dont think it will be that rich.

when I installed my surge tank it made bugger all difference to the AFR's...

Ok maybe just me, but I changed rail and regulator and I don't have pressure gauge to check what rail pressure I am running yet, but its up high to be safe.

Booked a tune in for it. Out of the Plazmaman and Process West tanks is there a superior? Both look the same from what I can see but do either of them have any problems with leaking?

I got a PW surge tank with single pump. Was running pretty rich up top but didnt notice any difference when normal driving. Had it retuned 2 days after fitting it to be sure.

One is a knock off/replica/copy. Do a search on this forum and see which one was on the market first.

All Process West surge tanks now have a second machined -8 thread on the outlet of the tank so that a second pump can be added with ease.
