5MGE acceleration problems

[drs77]

Okay, first off I have to explain. I don't own a Supra, I own a 4Runner with a (technically 84 Cressida) engine, but after visiting many places, including Supracharged, I haven't solved my probem. It seems that this site has the most knowledgeable people with these types of engines so here I am. Basically my truck starts good, idles good, revs good (in N). The problem is when I let out the clutch and go, it goes like crap. It sounds like air is billowing out the exhaust and it hardly wants to go up a hill. On a flat spot it accelerates a little better (still crap, I'm talking like 15mph in 5secs), but when it hits a certain RPM threshold, maybe 2500-3k rpm (don't know what it is, no tach), it takes off like a bat out of hell. I did all the usual tests and din't find anything weird. Since this eng is swapped out, I figured there might be some wiring issues. The only thing that I can think of is the fact that I didn't hook up the speed sensor. The reason being is that it is an A/T ecu, and the speed sensor wire goes to a box with about 10 other wires coming out of it that I believe go to the ECT box, which I don't need since I have a manual. Well, anywho, it's driving me crazy and if I can get some help I'd greatly appreciate it. Also, if anybody out there is planning on doing this swap, let me know so I can tell you some of the issues that I've had to deal with to make it work with a SAS, hi-steer, 3 core w/dual fans, and hood closing with no body lift....Peace...
