A little over a month ago I received my car back after a year being in the shop. Work done : New internals , Pistons , Head work and much more. Car has a Nismo tune with Dual Pop charger , 740 cc nismo injectors with stock turbos tuned at 8 psi. I broke in the engine 1100 miles. This is not a daily driver way too much money invested $$$$$. Car port and cover on vehicle with new body and paint. I am at my wits end because my oil pressure is good , Running right Air to fuel mixture and now I am starting to hear a little ping noise. should I drive it 140 miles back to the shop ? or get it towed.
