do you think a tune would help this setup alot
its a 2700 lb mustang notch ls1
th400 3500 stall
1 3/4 long tube headers
very mild ported 241 heads
zo6 cam
3:55 gears
cold air intake
30 lb injectors
think thats about it, i only drive it here and there not a every day car
A decent mail order tuner can probably get you just about as close as a dyno tune for no more than you have done. And depending on which tuner you go with it will probably be a better overall tune with mail order. And it would be much cheaper.
