hey guys,

i have an evo with a 2.2L block from ams and with 10.5.1 compression, it was used for laping and running on c16 gas , now i will used it a little bit more as a daily and wont use it at the track, I want to use pump gas, i have 94 here, with a tune will it be a problem because of the 10.5.1 compression ?
I heard i should use methanol and other tell me that i need to rebuild the engine to drop the compression ... , i am lost, does anyone had the same problem before ? Thanks
