One of the limitations of running higher boost is the stock fuel system. Upgrade to 550cc injectors from RC Engineering to get more fuel into your combustion chambers. Note: It is recommended that you pair an injector upgrade with an aftermarket fuel controller.
We also now offer their stock replacement 370cc injectors. OEM TT 360cc injectors are nearly $300 EACH (yikes!!) - these are drop-in brand new replacements for your old stockers.
NOTE: RC Injectors are special order and require about 1-2 weeks to get into stock.
