Blown Motor, Engine Rebuild/Replacement.

Complete speculation on your part. I say this because Mike Botti, MY tuner, tweaked my car with such incredible low and midrange power, that there was absolutely no lean spot or hesitation. No dampeners and no problems. Either that or this lean spot is a myth on the VVEL.

I've driven cars with weak spots in the powerband, yes. My G37 VVEL, with the GTM return kit wasn't even close to having a tuning issue.

I just couldn't let you dismiss a proven build with your own sales hype. I don't doubt the dampeners are a good idea. However, I'd found, and GTM delivered a product which worked famously. One ride in my car and you would have been shrugging in agreement. That is all.

I think cosmogirl has a very adequate system pending. For those who want 600whp+ a better fuel rail system is a must. That would be CJM and GTM. Both proven.
