Is your car heavily modified? I found out that the butterfly area of the vmax is modified. Most likely the cause of the problem.

Guys if you are experiencing ANY problems with VMax TB's please contact me direct I'd be glad to help in any matters. As with any product out there , there may be a few that were not lined up correctly when the CNC operator squared them off in the machine. However, this is unlikely BUT VMax Pete stands behind all of his products and I can take care of any questions regarding tuning, etc. on them (Really should not need a retune as long as your airflow tables are proper for your aftermarket mods OR stock).

With that said though, the VMax TB's are really nice. Remember you are spending $150 so it won't be like adding a supercharger to the car, but nice even throttle response and a couple of ponies for the money is plenty worth it

Sup guys, I bought a vmax ported throttlebody on here from another member as used working but when I got it installed the car would idle at 1500 or so. My car is full LG super pro 1 7/8 full 3" corsa, everything else stock as I will be having a H/C package installed and tuned in a month. I double checked everthing and all was good but still same results car drove fine but idles high so I re-install my stocker and its back to normal. Seller stated that I might need some tuning. I really hope I didnt buy a Lemon.
It does have a serial number etched into it and wonder if that is from vmax.

Matt, thank you for the help and clarification! Are you a supporting vendor of VMAX? I ordered mine through Norris Motorsports and Mike has been very helpful! Hopefully I can resolve this problem soon. My car has mods and ran completely normal until I installed the vmax. Going to make some changes with the idle tune and go from there.

Hi TW14,

Good talking to you yesterday and as you probably already know I talked to Matt at 21st Century MC and explained to him what was up. He said he would call you and get you in and it should just be a simple base airflow minimum adjustment. If not we will do what we can.

To let folks know, I told TW14 and everyone else that buys a 2005-2008 LS2 style TB (silver blade 90mm) that if it has been tuned due to a cam swap and the idle raised, that there is a chance it may need a recalibration of the final minimum air rate. We do not touch the TB blade bore area, but the transitions get some work. If the base minimum air flow is set higher then stock, then the blade will rest up more on this transition area and tend to hang a bit. The ECM will take out timing to lower the idle, but this is not the proper thing you want it to do. A proper re-cal is what is needed.

On the stock vehicles or stock tunes we have no issues.

Let me know.

On the one issue here from Canada with the 3200 idle, that is a definite issue and hopefully whomever you got it from worked with you on it. If not myself or Matt can help you out.

Mike Norris

This really isn't that big of a deal IMO. Have your tuner make some fine adjustments and it will run golden. I've have a few ported TB's and after a tune they ran like champs, snappy throttle response too.

good luck.
