How about none, piggy backing an 80's computer is never a good idea, unless your are planning on sticking with upgraded CT26

If you are going all out, then just bite the bullet and do a standalone. However, with respect to the previous poster, I ran a MAFT setup with 550's on my last car and was just shy of 500HP with a full T4 setup. I was also making 26MPG on the highway. No experience with MAP ECU however.

Ive used both.

Maft is faster to tune because you have the knobs to add/subtract fuel mixture on the unit itself, but minimal tunning points. allows you to remove afm and replace it with a ls1 mass air sensor and you could run it in blow through mode ( route it in your piping so the turbo looks nice by itself.

Map-ecu has more tunning capability, you have alot more tuning points, it hooks up to your laptop and you can get your readings and logs, you can also eliminate afm with it and go with an after market mass air. It takes a little gettin use to as any kind of tunning you do must be connected to a laptop in the car. Real time tuning and can hook up a wideband to it instead of it reading from stock o2 sensor so it will be way more accurate.

My decision would be map ecu. The power you make is more reliable than the old maft. and control more.

They both require the same amount of time to install (20-30 Min) for the average person. Only 5-7 wires each.

good luck.

If you want solid 450+ with quicker response/spool dont go any bigger than .74

.81 er .84 you wont hit full boost until 4800+ rpm, and since your going with a piggy back system you wont be able to rev past 7000 rpm so that only gives you just over 2000 rpm pull.

Just a suggestion as i went through the same thing thats all.

I understand, I made 565RWHP on VPC/AFC. Were my AF's high? Hell fucking yes. Could I flat my AF's? Hell fucking no.

Anything over that 500rwhp hump and it gets riskier on piggy back
