Haltech e6gmx plug in or delco map tune on 5.0l

[meni469]

Heya guys got a modified clubby cam 4 throttle bodies and rebuilt on the motor and twin exhaust system I heard that a stock ecu with a delco map would make more power and run smoother then a aftermarket haltech is this true or a myth ??? Any ideas

Stock ECU plus a proper dyno tune is the way to go. The stock ECU has all the tables and map that are specific to your car.

Also 4 throttle bodies?
