Unfortunately... not everyone can make it to Sharif with such ease Every tuner I've gone too has been a pain. Then every biulder I've been looking into has had some sort conspiracy/shut down since I've been shopping around. Actually, as I work my way outward from my location, I believe Forged is next (don't let me down! I'll be watching!)
But unless you're a Forged customer... I've run into the same types things. Talked to VQ owners who have babied their car every minute and that one time a week they have fun it's blown. I've know guys who ragged on it for 50,000 miles FI'ed and never had an issue. And some do blow in 3 weeks, some in 3 years. It's all about the tune, the maintance, the driving style, and common sense to know when you are pushing your luck.
Good luck FIVQ owners... we're all in this together

^^^I don't really agree with the above^^^
There is no reason that stock block forced induction, can't be 100% daily driver, and super reliable. Ask our customers, and the customers of other other tops shops!!
Many of our setups are going on 30-40K miles of trouble free usage.

NA motors just aren't made to have forced induction. Some can "handle it", but reliability and driveability, overall, go out the window.
The VQ35 block has never been the problem. That thing is stout as hell as is the crank. But those rods are weak and are made for quick revving and relatively high (sub 7200rpm) operational rpms. They're not made to handle excessive pressure or load. They're made to rev fast and be responsive.
The forced induction problems can easily be adverted by swapping in the rods, pistons, and rings. Expensive? Yes. Worthwhile if you want reliability. I guess I'm of the belief if you're going to it, do it right the first time and don't rely on some elaborate tune that drenches the chamber with fuel to quench excessive heat or pulls loads of timing. They're just band-aids, IMO.
Though our opinions differ on this subject, I still think your shop is kick *** and I totally respect what you guys do for the VQ community.
