injector sonic cleaning

[JDJames]

The caddy is a bit flat at the top of the rev range, and i hear that having the injectors sonic cleaned normaly gives a massive performance increase and makes the engine rev easier,on stuff that done over 50,000 miles, on k jetronic systems cos the injectors get gummed up and dont give the correct injection pattern.[?]
Anyone ever had it done?? i have a company nearby who will do it for me but i dont wanna waist me dosh if it doesnt make a difference.

I haven't had it done. I usually take a bottle of Redline fuel injector cleaner and dump the whole thing in when I have almost no fuel left in the tank. Usually cleans things up well. That sonic thing sounds cool. Wonder if it works, and what happens to all the junk that gets removed?

I had a sticky ISV, my mate gave me a litre of stuff to put into the fuel, sorted it, no probs since. I can't remember what it was called but it was from his workshop. I'll find out & let you know if you want.
