What are your supporting mods? I would be happy with 25 TQ too! Are these ported stockers or new CNC heads?

I only picked up 30hp and 20tq with heads but I also gained 5mph in the 1/4. Be optimistic!

Feels lighter due to the tq increase and seems to pull through rpm range quicker...

Well with +25 torque gain, +11 horsepower doesn't seem too bad given horsepower is a product of torque But as BFASTNOTLAST stated, let those ET's speak brother, be optimistic

That's not a bad gain for stock ported heads. Good luck man and get some passes in before the decent air goes away.

You know as well as I do that's still not bad compared to what we will be dealing with 2+ months from now.
4 months straight of 95+ degrees and >90% humidity...Yuck. Makes me nauseous just thinking about it. Almost as bad is not being able to keep your car clean and dry for more than 24 hours in a row in the summer.
