I have the chance to purchase a 16k mile IS38 and just wondering if it is “actually” worth the money and once properly mapped with my down pipe added, roughly what performance figures I could expect?

 

Has anyone done this yet?

 

Thoughts and opinions below please.

Revo and APR do a map for them, you can check the figures out 

 

@Ant-Vrs did it in THIS thread.

 

It is the same as any increase in turbo size, you will lose a bit of low down through slower spool and gain top end through more air delivery
