Not sure if this has been covered before on here but I feel the need to ask the question myself. After doing the deletes on my truck and tuning it with the MM3 through DRD I had a guy that lives near me that does alot of work on diesel trucks tell me "Do Not Use The Exhaust Brake Now That My Motor Has Been Tuned". He told me that since the motor is now tuned with my programmer that if I use my exhaust brake now that my chances of blowing a head gasket have increased a lot more than they would have if I was using the exhaust brake when my truck was left the way it was from the factory. Anybody got any advice on if this is true or not because if it is then I may be getting head studs sooner than I was planning?
