In a previous post I mentioned the following:
I have been having two conditions: pinging occuring while under load, towing 1200lbs at a max speed of 40 mph, on a 90 deg. day. Also, on a regular basis, when I get on the gas on the slightest incline from a stop, it hesitates at around 40-50 mph. I read that I need to have more than 1/4 tank of gas to prevent fuel starvation in this type of situation, so that wasn't an issue.
I have read that carbon build up can cause these symptoms..so I read about "motorvac" and inquired a FLM dealer about this service. They no longer use this due to higher solution cost & time required. They use "b&g" system now with good responses from customers. He claimed that it may even be better.
The Service Tech said that if I run 90+ octane all the time, there is a higher chance of building up carbon than if using 87 octane. When I asked about 87 leading to "varnish" build up, he agreed but stated to use an additive once every three to four tank fill ups. Also as many stated in this thread, a high volume, quality gas dealer.
Instead of using the cleaning service, he strongly recommended spending the same money for diagnostic service checking into the MAF & Oxygen sensors.
For the past two years, I have been using 89-93 octane, adding Techron to every sixth tank fill. Replaced fuel filter a year ago. Since I thought it was a trans issue I added a higher capacity b&m trans pan to aid cooling and increase fluid volume about 9mos ago(40k miles). Used genuine Mercon V fluid in a snap-on brand system that flushes out the old fluid at the same time replcing with new fluid. Shifting improved, same pinging. My car has the OEM trans cooler in between the ac & coolant radiators. Now I'm at 60k miles.
Would adding a larger radiator(is it possible?), additional trans cooling, carbon cleaning service, MAF & Oxygen sensor replacement, fuel change, ??? solve my issues?
Sorry for so many questions at once. Short of getting a "real" Marauder that has more power, what would you folks suggest?<!-- / message --><!-- sig -->

UPDATE:
Well, now the problem has been solved. I took the car to the dealer and had them do the "BG Fuel Injection Cleaning Service". What the heck, I figured that I would eliminate carbon build up as one of the problems before proceeding into diagnostics and parts. The results were amazing! I initially thought that the newfound driveabilty was because I wanted to feel the difference. The real test came when I towed my boat again in the exact same conditions as above. This time, I was able to go 75+ without any problems whatsoever. Starts & runs fantastic by comparison!
I would recommend this service if you are having pinging problems.
