Sonnax along with Superchips Flash
Not sure is this is a relative question but I'm wanting to use both on my 09 Hemi Overland. The Sonnax Trans pressure booster and the Superchips flash. I read that the Superchips made changes to the Transmission to firm up shifts but did not know if it boosted line pressure too. Don't want to over do it!
Thanks in advance for any advice on the matter
