my car was pretty modded except for the stock turbo...
like cams methanol kit, turbo back exhaust intake., mbc.....
im going to put all the parts back to stock.....
is it ok to drive drive with stock set up on previous tune?

 

who tuned it? most people will put it back to stock for free.

 

if you were running alky/meth and you're going back to stock, you definately need to re-tune back to stock or you're gonna blow up.

 

I Would Be Running Rich,,,right? Then Why U Say My Engine Is Gonna Blow Up?

 

????

 

yes, if you have all these mods you probbably have larger injectors and pump and they added fuel in your tune. by going back to stock your car will run way rich with the current map. and you risk the chance of washing cylinder walls as your car will probbably be wayyyyyyyyyyy rich

 

too much fuel can cause engine damage aswell, it can lead to washed cylinder walls, bad 02 sensors and more
