I spoke to RENNtech and they said the car didn’t need a different tune for the 19+ models. They told me same power increase. Maybe it’s a tad more because of the increase in horsepower for the facelift. Only way to know is to get these cars on the dyno. They are having there sale now and I will probably buy before next week.

Think about what you just said.

1) Why would a completely different physical equipment (turbocharger) not benefit from a different tune?
2) How can it have the exact same power increase? The pressures are going to be different
3) Since they don't have a different tune, why wouldn't they tell you that you don't need a different tune?

I don’t think it’s necessary or would be not profitable. Otherwise they would have it. It’s basically same engine as the 450. Some companies show horsepower gains from the 450 the same as the 43’s. Also every car can dyno different , gas is different and climates are different. Nobody will difference unless you dyno a 18 before and after then a 19 before and after. I don’t think the 20 horsepower increase will be noticeable. Especially if a slight remap was made on the 19’s to get the extra 20 horsepower. Hence same result.

The equipment itself is different. Why would a tune which is optimized for 1 turbocharger be assumed to work (in an optimized way) for one with another turbocharger? It is well known all these "tuners" are just a middle man for someone who actually comes up with a tune. It just isn't available, so they don't have it. And until they have it, they will just keep saying its all exactly the same, just different tunes

I think your wrong. If the turbos are bigger , maybe it’s just more efficient to make more power and less boost. The tune is then more advanced. Like a factory ecu tune installed. If you don’t like the tunes. Man. The piggybacks are even worse. Junk n my opinion. My tuner said said he tells all his customers not to trues them.

Hey I have a 2019 C43 Sedan and have been looking at the Euro Charge tune. How do you like it, have you had any problems so far or anything you don't like with it. Planning on just running stage one with stock performance exhaust and maybe BMS air air intakes. Thx
