Nyceboi I'll say this, Granatelli does not want to do any calibrations for a Tour', apparently they had to many returns that he will only do it on the basis that the consumer will not return the product no matter what the results are. I thought this to be of interest to you or anyone else for that matter, unless of course you plan on using some type of Fuel Management Unit which in that case the ProM would be beneficial as well as the CnL which proved to work great with the AFE on a mostly stock SVT no FMU. The ProM can be purchased flanged and will bolt directly to your stock filter housing. I can always install a AFE filter in the stock air box as another option. Removing the Airbox and going to a non-flanged unit like CnL or even ProM will help you avoid the cost of purchasing a MAF adapter, about $40 after shipping, and if you fabricate a Heat Shield the results will be much more beneficial than with the airbox. Even with out a Heat Shield the car will still perform admirably.
So to answer your ? I can't say what results would be attained with a ProM and AFE, I know that Dan Nixon got 12hp @wheels with a 9" Cone Filter, ProM and accordians removed from inlet rubber pipe and fortunately in his case the MAF unit proved very beneficial making over 8hp @wheels, the filter made only a few ponies. Dan did have exhaust mods and other intake mods to support those gains so I really can't say what the MAF and filter in his case would have done if his car was mostly stock like jjost...Aloha, Micah
