Hrmm then what would be the reason of it being ok on the stock engine at 280rwkw, but not ok with the new engine old turbo at 280rwkw. And then bigger turbo jumping to 315rwkw
Scotty can confirm this better than I, as he was watching the smoke out of the exhaust
But there were puffs of smoke im pretty sure when the engine would hit the "brick wall" on both 98 and e85
Also tuner did bring out the timing light during the tune to make sure everything was ok
Edit: Scotty too quick
