Re: Turbo buick tuning
I might have one somewhere done on L67 injectors with about 13-14 psi on an SC14 somewhere on my main PC. It was built off the tune done for a similar combo that 202 did on a Gemini too, the car I did a remote tune up was also a Gem. I never touched the spark as 202 already had something decent on his tune, but I did do the VE and few other things plus the injector data and flow to suit the L67 injectors.

Re: Turbo buick tuning
I just grabbed a tune from here,
viewtopic.php?t=375
This is a VN Turbo 2 bar tune. These are the VE tables. You can see how the VE increases across the 2 maps, the first map is the n/a map and the 2nd the boost map. (note that the 100kpa column is the same in both tables)
These are the timing tables. You can see as boost increases times decreases.

Re: Turbo buick tuning
Don't you also need to change the baro update?

Re: Turbo buick tuning
Would I be right to assume this tune is based on a 6400rpm redline?immortality wrote: Wed Jan 07, 2026 5:31 am I just grabbed a tune from here,

I see that on boost it has no timing above 6400
