Oh god...I hope so. Last year after a converter change and being told to slow down...or go home...lol I decided to finish the cage and when I took everything apart I decided to just switch to fast xfi...Matt gave me a great deal on his un used xfi 2.0 ecu...decided to just go all out. Added the parachute and made a few suspension tweeks. The current combo hasn't changed with motor setup mostly because I don't think I have even gotten a perfect pass yet. I went 9.48 and 9.13 with my last two passes...and never used the trns break yet. My 60s still suck...1.65 has been my best. But ran over 150mph....hopefully soon....once xfi is done I will need to re tune and hopefully not have to change a converter again...
