Just changing cyl volume will it correct the fuel map? And please explain speed density. You installing same map in the low octane tables? Where is GA is a good dyno tuner. I got jet dst and understand fairly but I know they are easier and better ways in any program.

Changing cylinder volume will not affect anything in your fueling. If you are going with a larger size engine and larger duration cam it will require a significant amount of changes to the VE, MAF, multiple idle tables, ignition timing, injector data along with MAP... definitely not a job for a first time tuner.

Find yourself some local help. Or else prepare to spend many hours reading and experimenting.

Hey dkiller,

I am almost finished with my H/C LQ9 tune, I could send it to you or something when I am finished up with it. Mine is pretty heavily modified. Forged motor, 236/232 on a 114LSA, AFR 225cc heads, longtubes, 4" Y-pipe, and edelbrock Pro-flo XT

But some of the things in the tune you should be able to borrow to get you started. VE map should be fairly close, as well as timing and MAYBE idle maps.

Let me know.

You are going to need a good datalogger.

Jet does not come with a scanner.
