Performance chip
The old adage, remains true in this case.
You need a legitimate tuner. Either someone local, or remove your ECU and send it to ECS.
Do some real mods then have it retuned. Lots of "tuners" that cant. Its literally like learning a different language, someone who is really good isnt cheap.

There are forum vendors that do mail in tunes as well as other tunes where you do not have to take your car to the tuner’s shop. These tunes can offer improved performance for your car, even on a stock platform.
And I agree with cuisinartvette - do a lot of research on who you want to do the tune to make sure you know their reputation for delivering a safe and reliable tune.






Not sure what all you were thinking about with the "performance package" (cam, heads, long tube exhaust or???), but you'll definitely want a tune after parts installation so if you're doing this anytime soon, I would suggest waiting and doing the tune to support your new parts. This will save on the price of two tunes, too.
Best wishes with your mods!

I have had several claim this to me and my response was "meet me at an ECS corvette Challenge and with an auto I'll guarantee 3 tenths or your money back". (cant do that with a manual, driver too inconsistent) Never had to give anyone back their money yet, but if you are doing this on your own you must make sure variables are the same. weather station, same DA etc etc.

A lean mix is worse for the engine.
If you think about a gas powered engine, you are mixing fuel and air in a stoichiometric air-fuel ratio (relating to or denoting quantities of reactants in simple integral ratios, as prescribed by an equation or formula is the fancy definition). This means you have to have the right amount of fuel for the right amount of air.
If the fuel-air ratio gets to rich (too much fuel), the engine combustion will get worse which causes inefficient burning of the fuel. This causes added hydrocarbon emissions, and excessive carbon build up, and lower engine performance.
If the fuel-air ratio gets to lean (not enough fuel), the engine has too much heated oxygen hitting the engine parts. The leads to excessively hot metal which is not good for the metal compounds. Also, since there is more oxygen, you have a quicker flame velocity which leads to knock or possibly engine stall.
You are hurting your engine either way, but the potential for engine damage is more significant with a lean burn which is why manufacturers will err on the side of rich instead of lean.
