Hey guys, I bought a 04 maxima not too long ago it was struggling due to the horrible stock timing chain tensioners. I went to replace it all (chain, tensioners, gears) in the middle of doing so I accidentally snapped my stock left exhaust camshaft. I ordered a set of tomei 274 pro cams for it and valve springs. In the middle of putting it back together now. Will I have to tune it for air fuel ratio or will it be fine without a tune? With that if having to tune it will a performance chip due the job or will I have to get a new tunable ecu? Thanks in advance!

 

I find it odd that you didn't think of these questions/issues prior to purchasing aftermarket cams...

I'd also be curious to see a link to where you bought said cams.
