Just Horsing Around
Hmm... Ok, so us old-and-tired engine owners would still be unwise to run more 15PSI then.The optimizer dosen't seem to mind it, I've run short bursts to 24/25 but a steady diet of 20lbs. seems alright. I've put 20 thou on it running that boost.
You mention you are (or plan to?) do a lot of towing with the truck - was the turbo change primariliy to benefit the towing ability? If so, how were the results versus the GM8?
Fuel economy better/worse while not towing?
