I have a question about the AFPR. If I have a Stage 3 MAF, boost enhancer, Free flow exhaust, Shimmed wastegate, and MSD igntion, should I buy a AFPR.
If I buy the AFPR what will that mean for the ARC-2 that came with my MAF. Will it effect that any. And if it does will it be good or bad? Will it be more rich?

Today i almost lost my car. I was leaving school, and a van pulled out infront of me when i was turning. The F-cker came withing inches of me. But before SHE did i spooled up my turbo and was running about 14 PSI on my boost gauge. I lost control and spun out on dry cement infront of the park after fishtailing for about 20 feet. I was scared ****less. SO MUCH POWER. My cousin was behind me, and he couldnt believe it. He was amazed. Anyway, Im still trying to cope with it.

 

A afpr can be adjusted to a higher psi so you could make more hp and not run lean but it has its limits. Together with larger injectors it can be used as a tuning tool for adjusting a/f with your maf,if it has a fuel controller on it.

 

So If I were to buy one would it be wise even though i dont have larger fuel injectors and dont plan on buying bigger ones at their price.

 

If you already have an ARC2, you don't really need an AFPR. Tuning the air-fuel curve is much easier with the ARC2. The AFPR will just scale that entire curve up or down, but you can't change the shape; which is typically way too rich in the mid-range and too lean in the upper-RPMs.

Save your money and just buy a 3-bar FPR from <a href="http://www.paragon-products.com" target="_blank">Paragon Products</a>.
