I know its risky, but i have the mods listed in my sig and have been driving untunes for a couple of weeks due to not having money for a tune bc the wifes tranny in her explorer had to be replaced. But ive had no isses other than running rich. Car hasnt stalled out yet!

 

I'm about to run into the predicament. I want to do a mail tune with a 224/224 cam for while I get heads and supporting parts together before a dyno tune.
