I'm looking to upgrade from my he351. Truck runs far too hot with the new injectors a dv's. I'm looking for a fairly quick spooling turbo but not expecting as fast as the he351. Also hopeing for something that will work as a good base for a twin set up. Looking for around 500-575 on the single and will control my egts better and possible to tow maybe 15000 lbs with.
