so i blew my old engine and i had it tuned by english racing and i got a new motor swap didn’t change any of the bolts on they stayed the same do i need to get a new tune or will i be fine with my old tune ?
PLEASE HELP ASAP

 

Do you know why it blew? If it was too aggressive a tune, you'll want a new tune.

 

No 2 engines will run exactly the same even if they are built to same spec. the tune could be safe enough that it's ok but why risk it? Re-tunes are usually half the cost of a full tune as well so should only be a couple hundred bucks for the piece of mind knowing the tune is good.

 

If you are using the same parts, chances are you are good to drive on it as long as you stay out of boost. You aren't using the same oil cooler correct?

When you get into boost is when you will start to see differences and will need a retune. English Racing tunes are rather solid so I would think that the engine failed due to other factors.

 

the engine blew cause we were messing with the cobb access port and switched to a stage 1 cobb tune and did a pull and blew the engine it was my fault

 

yes i do it blew cause i switched to stage 1 cobb tune on accident and blew it

 

it failed due to switching to a stage 1 cobb tune and i called english racing and they said id be fine and good to go thank you
