I'd go for some of this: http://www.auto-rx.com/pages/pov.htm

It's a gentle cleaner that liquifies sludge and thus unsticks the piston ring packs to improve sealing. It is also used in $30 million printing presses.

Auto-RX has worked great on my Sienna, Land Cruiser and Legend.

JIBBBY,

What shop did your installation? Do you recommend them?

I'm in the OC, so not far from you.

Thanks!

It's called an ECU piggy-back system and not a chip....What it does is attach or wire up to your stock ECU (cars computer brain) and allows you to increase the stock setting of fuel and air mix that is delivered to the engine...Hense more fuel and air give you more power...The most you can expect to gain off this mod is maybe 15hp or so and not 30hp... Stock settings are restrictive as is with most cars.

You can also send in your stock ECU to be recalibrated...There are a few companies that do that too..I don't like that method for tuning reasons alone...

You can expect a ittle hit at the pumps but not much if any......

Apexi piggy back ECU is what I use....Decent...$500 installed and tuned....

and many others out there.......
