I dont think German Muscle is trying to be rude in his post or try and play any cards... he is a local to me and he has been by the shop alot and seen me modify engines, test engines, do alot of R&D etc. He has seen alot of things 1st hand and may have just come off wrong to you. I dont think he means any harm to you or any modifying company out there. Heck if were not always trying something different and testing it, then these engines wouldnt keep getting better. Look at the engines even 5-6 years ago to what they are now. I can promise you they didnt get better over time with no experimenting/R&D. I know I do ALOT of it. But thats what its all about!
