Perhaps Jim, however running then boost I do creates a lot more exhaust gasses to expel as I thought going into this project. It has never spun into 3rd gear before. I'll be checking mileage nest to see if it goes up an appreciative amount. Honestly it screams into 3rd gear which it did not do before. I am quite pleased except it could be quieter form my taste. Influenced by the sound......................maybe but the tach is my guideline and it comes on quickly. Too bad I could not have done a before rest with the set-up. I am quite pleased nonetheless. Regardless I feel the extra power and will get to s dyno for some numbers to see if it lines up with guys with similar mods, mark
PS: I am in SW Florida where it still has it's hot days and still it pulls hard. i want to do a thermostat mod so coolant, how little flow begins at start up. From what I can tell drilling 4 holes the size of a nickle would do the trick and have the fan operate at a sooner temp number or have it hot wired to work whenever then car has then motor running.
21psi makes ma lot more spent gasses to evacuate. Then running into the Magnafloe TRU X-pipe internals is a great piece meant to even then uneven flow of the V6 motor dumping inrto the magnaflow "Y: and 3" back yo the Borla. I could not believe the weight of the stock resonator and the muffler were! If the mileafe goes up I will use that as part of my defence of the project.
