Subaru FA20 Upgraded Turbo

This option is for doing a tune on a Subaru WRX with the FA20 engine with an upgraded turbocharger and any supporting mods.
 
Add ons:
 
E60 ($250)
Add a separate E60 map.  We strongly recommend an upgraded in-tank pump to do an E60 tune.  Blending to E60 requires using 2-3 gallons of premium fuel and the rest is E85.  Our E60 tune can handle a good varience in the blend so you just need to be close. E60 can add up to 50-70 whp on an FA20 engine depending on modications.
 
E40 Map ($200)
This option will give you a tune for an E40 mixture of ethanol and gas in addition to a regular gas only tune.  An E40 mixture is done by mixing half regular premium fuel with half E85 at the pump.  It is safe to do this with any modications and even with a stock in-tank fuel pump but can upgraded pump can be done.  E40 can typically add 30-50 whp depending on modifications.
 
Burble Map ($50) -
This is an extra map that will give the car a "burble" or popping exhaust sound when coasting in gear.  The feature is active above 3000 rpms and only when coasting (decellerating).  The effect and sound will depend on your exhaust system.  The more open it is, the louder the effect.  Stage 1 cars or Stage 2 cars with resitricive muffling may not be able to hear the effect very well.
