I have a 95 accord ex with the 2.2 vtec, I found a chipped p28 online that comes tuned to your specs. I have aftermarket headers, and cold air intake. What would be a good tune? Vtec, redline, disable 02 or knock, ?

 

Do not waste your mony on a chipped ECU. Unless you plan on doing more to the engine and having it tuned on a dyno. A chipped ECU with a basemap tune is a waste of money for bolt on mods on an F22B1, i.e. intake and header.

Changing the VTEC will not gain you anything and nether will raising the red line. These engines only make power up to 5500 PRM anyway and the VTEC crossover for the stock camshaft is tuned very well from the factory. Why would you want to disable the O2 and knock sensor? Disabling them is not a wise decision....

If you want to get your car tuned take it to a reputable tuner that can properly tune it on a dyno and then on the street. That is the only way to get the most out of any modifications that you make to the engine.
