My GTP got 6% better MPG after already having a cold air intake and it cost $1 at Radio Shack and any Joe can do it in 1 min. It will think your air intake is always 70degrees. It thinks the air is richer and uses less fuel to keep the preset air to fuel ratio at 14.7. I have noticed no change in HP though. Also u can pop the screen out of the mass air flow sensor for air flow. U can build u a RAM air intake for $40 at O'Reilly's. U can get or make a crancase breather to save gas. U can catch blow-by with a cheap Mason jar if your car has a vaccum line off of the PCV valve which will also help HP.
When I used to drive my 03 Malibu it got 8 MPG Hwy over EPA after my mods for $50 and a great HP improvement.
Zmaxx also makes a big HP improvement. Hope these cheap tricks help u  |
Hi, i just read your post with great interest, i have installed an HHO generator on my Audi and have a real HP boost but i am not seeing the MPG increase they claim. now i am thinking of installing a Volo performance chip to increase MPG, the HHO company said i should use a 02 sensor extender, but that is real hard to do on my vehicle. Do you think a 3.3k ohm resister will work for me with the HHO?
Any help would be greatly appreciated
Andy.
