Worked great on my 2003 VW TDI Jetta with a turbo lag. Before I used this it would be very underpowered and turbo would kick off at 45-50mph. After I installed this it had significantly changed throttle response and torque. The turbo would then kick off at around 63-68. Absolutely love it will be ordering one for 05 soon!👌😎😎
I put one in my KIA 17 KIA Sedona WoW! If I am not careful when I press on the accelerator pedal it starts squealing my tires, its fast and the torque steer is insane, so I must be careful not to turn the wheel if I put the pedal to the metal! This one is a V6, I just ordered a stage 3 for my 17 KIA Sorento 4 cylinder .
Purchased stage 3 tuner for my 02 blazer and I immediately felt difference in power.My blazer idles better and everything.Very pleased with this product!
Bought the 100$ stage 3 chip w the interface to monitor data. I kid u not, I gained over 100hp and gained roughly 150ft lbs of tq!!! I have a modified RS Chevrolet Cruze which comes with 150hp.stock and 160ft lbs of tq stock. I wish I could post screenshot of data so everyone can see I’m telling truth! Now I only have had one tune done to car and I need car tuned more badly as car isn’t able to get more HP due to the current tune I have in car. Basically ive got over 10 performance upgrades and mods so car is very confused but like I said I’m still getting HP and TQ without a updated tune. With correct tune I believe car will get 300+HP!!! I highly recommend product
I’m extremely happy with my chip the acceleration is amazing the throttle response is good too
