How much more power should i expect to gain from a dyno tune with a custom burned chip? My wife is letting me get a dyno tune with a custom burned chip for my birthday and i was undecided whether i wanted to spend the money on that or spend it somewhere else. My current setup is Edelbrock Performer HCI 24# injectors 70 mm BBK TB 80mm ProM MAF TKO 600 355s on a A9l computer. the dyno tune and chip is going to run around $400 just trying to spend my money wisely
