Post Dyno runs. Good and bad 2003 SVT lightning

Ok did my dyno tune. What a LONG day.

OK, mods done before shop so I had no baseline.

Mods: C & L upper intake, Acufab single blade TB, C & L intake tube, C & L 95mm maf and air filter. 4# lower pulley kit & colder plugs.

After 12 pulls( 19 deg timing ) we go a max HP of 381 (sae) 389 (std) with 478 tq. Only problem was the 95mm maf was making the Air mixture go nuts it would drop to a rich 10:1 or lower. Hence the 12 runs and 12 chip flashes. So we went back to the 90 mm maf(stock) and used an adaptor plate with the air filter. Results on runs 13 & 14 was 380 hp with 458 ft lbs of tq(19 deg timing and 11.5:1 fuel). It seems I'm the 1st person in my area to have the 95 MM maf and the programs available didnt have the specs for the added air. So, after a call to C & L and to superchips, we have the datasheets for the new maf and by next week will have a usable program to put on the chip. looking to make 400HP at the rear wheel. with either 19 or 20 degs of timing. keeping my fingers crossed.
