my car is completely stock except for a brand new lower end. If i take it to excessive and have it dyno'd would i gain anything if they "tuned" it? Should i have A/R printed out also? How would they tune it....what would they do?
I guess if its not to much I would do it,but you never know what they will find.You might drive out with 20hp more,or you might only pick up 1hp and 5ft-bls of torque.It all depends on the price and how the car seems to run now.
Also,you say its a new bottom end,is it broke in yet?
You might want to wait till 1000 miles just to be safe.The rings may still be seating and bearings setling.If you go now and your not fully broken in yet,you power numbers will change,possably even your tune.
