Product Description

Highest Quality TGV Deletes that anyone can afford!

Dont feel like spending $500 for a new set up butterfly-less tgvs or $600 for a JDM Intake Manifold? For less than 1/2 the price you can get the same exact benefits from our TGV Deletes. In this process we take a stock TGV and completely gut it, which includes taking out the metal plate, butterflies, and bar. These will allow for maximum flow through the TGV. Minimize the engine's heat from entering the TGV's with our ceramic coating. It is very important that heat stays out of the TGV's because this is the last transfer before the intake air enters the engine. Cooler intake air equals more hp.

Customers have seen gains of 15+ whp/wtq. We've also seen third party flowbench tests showing an increase from 330 cfm to 480 cfm!!

On a typical STG 2 setup you are going to realize an increase of 5-10tq/5-8hp in the low end, 10-15tq/8-12hp in the mid range, and 5-10tq/5-8hp at the high end. As you can see in the dyno graph, max gains are going to occur in the mid range.

As far as where the gains occur in the power band, your entire power band is going to see an improvement with our TGV Deletes.

Note: This is a TGV Delete Service for two (pair) of TGVs. If you do not add refundable core you will need to send your TGVs to us.

These will also give you a quicker turbo spool up. If those gains weren't good enough for you, wait till you add a bigger turbo...the bigger the turbo you put on the bigger the gains are going to be from getting the GrimmSpeed™ TGV Delete.

As always, if you are not sending in a core to get deleted, you will need to pay the core fee. You will get this money refunded when you send your old stock pieces back.

Because of labor intensive purposes porting orders can take up to 3 weeks to complete. Please contact us ahead of time with any questions or concerns.

  1. the standard for all TGV deletes

    Posted by JL

    Very pleased with the set of TGV deletes I received. the parts were clean, motor and sensor holes were filled, and port work was top notch. Internal surfaces were smooth and consistent. Also had GS logo etched on the top in the middle, a nice touch. As with all other GS products I own, no disappointments here.


  2. Awesome!!
