Ok I'm trying to figure out why this was done, I have a 347 EFI with 10:1 compression and the previous owner had it dyno tuned with 110 at Anderson Ford motor sports in Clinton IL. Any ideas of why tune a car with 110 when it don't need it and what kind of gain could I expect if I switched to pump gas?

Thanks
Mike
 
Likely that guy was a persistent idiot, and the shop took his money. Of course someone at the shop could have talked him into doing it because "hey its RACE FUEL. It has to make more power". ← Sarcasm...... Unless it was going to be purpose used as a power adder engine, like he had a nitrous kit on it or a blower/turbo, then there is no point. Are you sure the guy didnt have any power adder on this engine, and maybe took them off before putting the car up for sale?

This. I know I would take a kit off a car I'm selling.

does it have a PMS piggy back or a chip?

i only ask cuz you said anderson......if it has a PMS system, there could be 3 tunes inside, and maybe one of them is the pump gas tune.

this is how i have mine set up atleast....tune1-Racegas, tune 2-Pumpgas, Tune 3- is my play around with it tune area so i dont mess up my 2 others.
 
Is it 110 or C10?

Could be it was a class built car and it was a spec fuel. I know when I ran Factory Stock we had to run C10 which was an unleaded race fuel. There is not way my "stock" head "stock" cam no compression 302 needed that fuel but it was what we had to run and tuned accordingly.

Neither did my 9.1:1 stock Explorer engine need it BUT, I did pick up HUGE amounts of torque by being able to crank in a ton more timing on the C10 after dialing in the tune on it!

That crap is NOT cheap either!
 
I want to start by saying thanks for the replies. Car was my father-in-laws car (wife's dad) and he did have $ and I think they talked him into it. It was a bracket points car at Cordova so I'm almost positive it didn't call for a spec fuel. No power adder was ever on the car (only been finished the last 3 years) It does have a PMS piggy back but I haven't ran the car or turned the ignition on to see what it's all about. It has a bunch of controllers on the passenger floor that I have no idea what they do :-( He was an electrician by trade so wiring was his thing and it's my weakness for a car. He passed away back in Nov. and my x-wife's sister told me he passed and the car was going up for sale that's how I ended up with it. Couldn't pass it up for the price compared to what was for sale out there. I can't call him for info so it's a huge puzzle that I'm putting together. So is it worth spending $800 or so for a new pump gas dyno tune? I'm thinking about putting a 100 shot on it but that putts me near the limits of the stock roller block
 
Better safe than sorry especially considering it's a 347. I'd say the tune would be worth it

tune it urself man. thats what the controllers for. bet it still has the correct tunes in it, you can just play with them

i have the user manual for the PMS cuz i have one in my car and i learned alot from stangtuning.net.

i have a piggy back with the low inpedence injector driver.
 
why not call anderson and see if they have any inside info on the car they may be able to share. chances are since they tuned it they may be able to give you some info on it if they remember

That thought hit me last Friday lol. I figured they have to have some type of file and I do have about $1600 in receipts from them
