Lexus AFM upgrade ??Wait or toss it on??

Supra Saiyan · 12-21-2010, 06:57 AM

So if I take my 7mgte supra that has the following mods..

3'' cat back
AEM intake

So if I was to say~.. What if I did the Lexus AFM Upgrade????
Would that be ok or will I be throwing the whole system into shams?

I just need the Lexus AFM to do the mod right? Is it a direct swap?

Direct drop in yes...

Without fuel pump and 550cc injectors you will run lean. It basically allows more unmetered air into your engine.

^ agreed. you could bypass the 550cc and get an safc but you would need a AFR gauge to see how much to increase or decrease

You don't need an upgraded pump for this mod, the stock one flows more than enough. You DO need to be 100% sure yours is in good shape (so might as well replace it with a better one anyway). As mkiiisupra said, you must install the injectors first or prior to the AFM or you will run lean at WOT.
