Hey guys! Hope everyone is staying safe during these times! 

Got another query, I don't want to ask these questions to vehicle remappers as I don't want a bias opinion to sway me to buy a remap as I know I'll only get answers I wanna hear like "it's risk free" etc

But what actual damage does "pop and bang/pops on deceleration" maps do to the car? 

What pros and cons are there to stage 1 maps? 

I know the purpose of a stage 1 is to only unlock the power left by the manufacturer. But manufacturers must of capped the power of these cars for a reason right? 

I have a fiesta mk7.5 140bhp red edition with cobra non res exhaust and stage 2 induction kit with turbo hard pipe and was looking to add a bit more excitement to the setup! 

Cheers guys! 

For the love of god don't get a pop and bang map on a 1L fiesta 😂😂😂

The biggest thing to worry about with these cars is the gearbox. They're not really rated for much more than 140hp. Like most car parts it's a lottery as to who's will wear at what power. Some will last above 200hp, others will go at 160hp.

Pop and bang map will destroy your cat (no not your pussycat 🤦‍♂️) in no time. It's unburnt fuel that gets ignited in the exhaust so also doesn't do the turbo any favours...

Having said that, you'll probably be fine with a regular stage 1 map. Just dont launch the car everywhere you go, warm it up properly before ragging it, be prepared to service it more frequently and only use v-power or equivalent (the map is specifically tuned for the higher RON).
