When you do your timing belt, throw on a Cobb lightweight crank pulley. Got mine on NASIOC for under $100 shipped.
If you're doing engine performance upgrades, I would say it's worth it to help keep an eye on the newly installed mods.These aren't entirely necessary though. I personally would not spend the money just yet.
My $1,000 (assuming suspension-wise the RSB at least is done to a 19 or preferably 22 mm, and that the DP and Cobb AP aren't coming out of the budget) would be:
- Used aftermarket TMIC (TurboXS, Process West, etc)
- Used VF34/43/48/etc.
- Pro tune (even if e-tune)
I was surprised I over boosted my TD04 today with just switching to a lightweight crank and catless up-pipe. CEL came on with a P0244 code, apparently over boosting is the only way to get the code based on my research on here. So gauges are now on my 'To Do' list, despite my short mod list.I'm not saying don't get them, just not yet; a VF turbo, TMIC and a conservative tune are, IMO, not straining the engine too much, if at all. If a larger turbo was going on, or there was a plan to ring the neck of a VF, then yeah, boost and wideband gauges are important.
Might be a difference in ECUs capabilities, but I don't have either boost or wideband gauge on mine (yet) with VF52, TMIC, fuel pump, silicone intake, TBE and tune (only 230 whp though). I can log all parameters needed to check, quite adequately.
I'm getting a more aggressive tune shortly, so wideband has been bought, but just not fitted yet...
