just watched an interesting show on speed channel.....had an expert on turbos discussing boost......he said a 1 lb. of boost increase is worth a 7% increase in horsepower.....interesting.....might have to break down and roll it up!

i,m feeling kinda stupid about this but....i recently posted about a lo blm condition and the solution was that my maf screen had come loose and obvously the cheap plastic retaining clip was loose in the filter also. luckily nothing sucked beyound the maf. like most my screen is held in with a...

I have done the searches etc. but still am confused. My idle blm has suddenly dropped to 110=115, cruise at 110. Never have had a problem before, but I did run leaded 110 at the track, they were not selling unleaded 100 as in the past, just as a precaution. I had never done this before...

guys, give me some advice, I am trying to make my stock gn as fast as I can in basic stock trim, street tires and 94 octane, I just ordered Erics chip (very nice) for stock injectors. The programable feature is very interesting. Should I add or subtract fuel and or timing, and in which gears...

Guys, am thinking about adding a dut neck. What effect does it have on boost levels. I run a turbotweak street chip 94. Boost level peaks at 16. I get 0 kr on 94 pump gas. Just wondering how things are going to change witn the neck.

Guys, any suggestions for a good street chip for a basic stock setup. I used to run a hypertech stage 2 and got laughed off the board, however on a recent trip to the track it was .25 faster than reds 93. I did this test on the same day and identical conditions with similar 60ft time. The...
