What is the most power any tuner or person has gotten out of a GT w/ the stock MAF and airbox? Is it about 320-330 rwhp N/A ?

 

According to Lidio from Alternative Auto ? he has a custom tune for the stock airbox that provides 20 additional HP over the stock factory tune..So you may want to ask for his opinion directly for further info..

 

The 5.0 Mustang magazine that tested a bunch of CAIs a few years back showed that a stock airbox + K&N panel filter + SCT tune netted roughly 14 hp over stock. I'm not sure what Lidio did to step it up a notch with 6 more ponies, but it will probably cost a pretty penny to find out

 

A phone call surely doesn't cost you a pretty penny ? just let him know your input concerning the stock airbox and ask him for some advice at least this way you'll have some of your questions answered..and who knows ? maybe he'll be willing to give you a discount on both the X-Cal tuner and stock airbox tune..it's possible that you could get both for under $400.00 which isn't bad for both an SCT programmer and 3 custom tunes..

 

I have the stock airbox with K&N filter and Doug's 91 race tune. I don't know how much horsepower I gained, but it must be significant judging by the way that it accelerates now.

 

Here is a cut and paste from one of my posts on another site.

3 runs were done with each configuration.
1/2 hour cool down time between runs.
The MPH is always high at that track by 2.5-3 mph.

I actually did back to back to back testing.
Stock VS. 93 Octane Diablosport Canned tune VS. C&L Street Kit and 93 Octane Diablosport C&L Canned tune.

The results were

Stock intake and stock tune 2.094 ft. 13.757 @ 102.630 mph.
Stock intake and Diablo 93 octane tune 2.041 ft. 13.535 @ 104.577 mph.
C&L Intake and Diablo 93 octane C&L tune 1.954 ft. 13.274 @ 107.453 mph.

The car went on to run 12.95 @ 103 on the brakes with BFG Drag Radials later the same day during eliminations.

My 1/4 mile times were within 0.015 between this track and Englishtown NJ. with a comparable DA
