TJ's case is particularly interesting but it is also unique because he did what everyone here -quite properly- harps about, he tunned his car. In the process, changes such as his A/F ratio create conditions that, were he to go instantly back to pump premium, would be uterly disastrous. It would also make girlieracer's blab about purposely blowing up a D seem trite because TJ's would be spectacular ( I think girlieracer missed a shift but TJ has a turbo that would be blowing into a lean engine.) Since I am not familiar with the range that the ecu can alter the mixture, I really can't comment on what would happen if he increased the spec grav slowly. I would speculate that it would work up to some point after which the computer could not compensate for but it may be instantly spectacular or it may not, I really can't say.7thGear said:id love to do it
but let me freakin finish my minime first!!
on a side note, you said that going back to pump gas after using the stuff requires retuning, what if you gradualy reduce the dosage mixed until your back to using 100% regular gasoline?? would that be okay
seems like a nice thing to do with an engine thats dirty... but then again seafoam is a tried and tested product.
