Yea, I would wait to upgrade the turbo and all if that is what you plan on doing anyway. I am upgrading to a MAF this winter but won't be getting a new turbo for at least 1.5 years. Plus, I have some other upgrades that I need to re-tune anyways. If I were you, just get a used AFM in there for now.

So wait, you would recommend doing it all at once, but you are doing it MAF first, then turbo in 1.5 years?

I guess getting the used AFM is the best option financially for me right now. I haven't had the time to research all the upgrade options and if it's worth getting just the MAF without the turbo, but I thought I had read some reports that the results were around 325whp with just the MAF/chips upgrade from Vitesse -- is that not right?

Personally, I don't see how you'd get over 300rwhp without larger injectors as well. I'm hitting the limit of the stock injectors as is right now. I'd stick with just replacing the stock AFM for now and then save up for doing everything at once.

The most I have heard is about 300RWHP with chips, testpipe, wastegate, maf and being well tuned. The reason I can going to get a maf before I get a turbo is because I don't have the 3K to spend on it for awhile. I can get a maf and piggyback to tune it then wait about 1.5 years before I go to a new turbo, but who knows, I might be happy with the maf and a good tuning. My afm is good just would like to clean up the air/fuel ratio and be able to tune myself.

Used = old, offer them $100 or buy two on this site for $50 each. $350 is probably not unrealistic for porsche shops.

Are all 951 AFM's the same regardless of year? Mine is an '87.

Evan70

Yes, they should all be the same for 951s.
