Have any of you guys installed gauges or monitors. I am considering a boost gauge along with a fuel/air gauge. I have also looked into hp monitors such as Gtech. Any advice would be helpful. I am still contemplating the Powerchip. For the longest time they would send me emails telling me how much of an improvement I would get but when I mentioned that I was almost ready they said around a 8 hp gain. Renntech has always maintained a 7 to 8 hp gain which seems very realistic. Powerchip does offer a 14 day money back gaurantee. With the ASP crank pulley, Green Cotton air filter, Supersprint header/muffler I am wondering how much more HP I can realisticlay get out of the inline 4 without going the camshaft route. Any input will be really apreciated guys. Deathy, sorry about the car. That blows. Any word on how much the reapirs are?
