Just browsing the Topbuzz website and came across this............

http://www.ecotekplc.com/products.htm

Anyone tried these products?

Seen these before....

Not sure what the CB-26P does really.

Powerboost promises to de-coke engines, which is OK if the engine needs de-coking in the first place. A reasonable-mileage well-maintained engine where the mixture has always been correct (e.g. all sensors working, plugs and HT in good condition, clean injectors, etc) should really not have too much carbon deposits in the first place so will not benefit from this product anyway. So I would give it a go only if I had a high-miler with knows carbon deposit problem, and as a last chance before removing the head(s) for proper de-coking.

Ekotec100 is a PTFE (Teflon) additive, so you have to ask yourself if you really want it... there are pros and cons, but without going into this (I am against BTW...) if you really want it then the most common product is Slik 50.

HTH.

Apparently the CB-26P sits on one of the vacuum pipes:

'it collapses the manifold vacuum allowing briefly for a richer mixture on the re-application of a trailing throttle - thus significantly improving throttle response - and it creates an element of off-throttle turbulence'

and it looks like it has a small Piper Cross air filter.

Total snake oil. Wouldn't touch it with a barge pole.

Spend the money on petrol instead, I say.

Sorry, couldn't leave it at that...

I've never read such a load of horse sh!t.

Collapses the manifold vacuum = unmetered air leak = bad news

Richer mixture on re-application of throttle - No. Vacuum doesn't make any difference to the mixture on an Omega. MAF, TPS and rate of change of TPS are the main factors that determine throttle response and have been carefully tuned by GM to do so. Some chavvy valve in one of the vacuum lines is going to improve this, is it? Nope. It adds unmetered air which will lean the mixture and, at best, worsen throttle response.

off-throttle turbulence ?!?!?!. There's very little airflow at all into an engine off throttle. How turbulent it is doesn't make any difference because in most cases the ECU will have completely shut off the fuel at this point unless then engine is idling - meaning the air will just flow through the engine and out of the exhaust. Whether it does that smoothly or turbulently isn't relevant.
