tuning for faster spool up
tuning for faster spool up Whats the general rule for getting your turbos to spool up faster. I had the car tuned with smaller turbos when I converted to a 3bar map setup. I upgraded to slightly larger turbos and the car is a pig off the line. I know you will have more lag with the larger turbos, but in this case I believe I can spool up faster with some tuning. I have efilive so I can change anything I just need some direction. My logs show the afr during spool up to be 12.3-12.5 from 0-30mph once in boost I drop right down to 11.5 on the car hauls ***. I was thinking of adding fuel down low to get it going. Is this the right idea? This is a sts kit so the turbos are in the back. I went from a .36 a/r exhaust housing to a .48. On the compressor side I went from a 47 trim to a 52. Any sugguestion would be appreciated.

I realize this is a 10 year old post.
Just curious how that worked out for you.
Did you ever get quicker spool up from playing with the tune?
I've got an STS kit too. Figured I'd give the .48 housings a go and ended up putting my .36 ones back on beacuse of the lag.
