Tuning Tips and other suggestions

Used only on the 03/04 Marauder but can be used on any 03/04 ecu with code changes. Uses newer style SCP array so will not control cluster correctly on 2004 and older fords that use the older style SCP array such as mustangs.

So I finally put some timing in the borderline table which looked like it basically had none in the base custom file and it really woke the car up. I have a low compression block with room to grow for power. Head studs, cooling mod and DA/DB heads are present as well. I’m running on 92 pump gas. Right now the car has stock blower pulley sizes on the drive as a factory 03 cobra. Similarly it has stock sized 39 lb injectors and a stock (Hitachi) MAF. I have a 3 inch pulley I think I’d like to try for the Eaton. I think I’m going to run out of MAF so I’m wondering what MAFs are recommended, is it time to go with a slot setup? Also, what kind of timing changes if any are needed/recommended? I’ve been considering possibly going to a whipple 2.3 at some point if it will fit under the marauders hood so maybe Siemens 60lb are a good idea as well? The power curve has changed so much I’m also wondering what transmission shift strategy parameters could be changed for more ideal operation. I’d like her to kick down quicker at times and stay in some gears during acceleration. Any thoughts and or feedback are appreciated. Thanks

yep always slot

low compression 4v on 8 lbs id shoot 21 deg to her up top

might as well get the 80s over the 60s they are backordered though

just basic tuning shift speeds
