need help with mass air conversion

[Superpromustang]

I converted my 88 stang to mass air the cheap way, I got an 89 wiring harness out of a salvage yard, and I'm using a 90 EEC, but now I can't do a running test on it, is this because of the difference in EEC's? It seems to run okay, 347, trick flow 10.5:1 pistons, trick flow track heat heads, steel crank, GT-40 intake, with lower port matched, 75mm pro-m MAF, 24 lb injectors, 65mm TB, Moroso cold air, Dynomax medium length headers, AOD w/transbrake, 9.5 stallion converter 3800 stall, aluminum driveshaft, 4.10 gears, and 28 X 10.5 Mickey T's, best time to date is 11.74@114 in the 1/4 and 7.23@94 in the 1/8. Any feedback would be greatly appreciated, Kenny
