Hey everyone,
I'm looking for someone that has experience tuning Grand Prix's in Minnesota, preferably in the Twin Cities metro. If push comes to shove, anywhere in MN or WI would be alright.
Does anyone have a good shop or private party to recommend? From what I have heard, most shops have little to no experience with the 3800's. I don't have an issue with street tuning as long as it's not in a highly populated area.
Also - tangentially related to this - when under WOT, my power drops through the floor at around 6k RPM. I believe I have stronger strings, but am not 100% sure... What are the chances this drop in power is due to a poor tune causing me to run way too lean and not due to valve float?
Thank you in advance!
