I'd tend to agree with your friend because the supercharger is definently louder in second gear than it is in first.Redline686 said:This may be the wrong thread to mention this but I heard from my friend at a dealership that when he was testing out his redline the person working on his found out that it may be limiting boost in first and second gear. I doubt this would show up on the boost guage, its probably releasing boost after that reading. Can anyone verify this or can anyone please tell me I'm wrong. That would be skeet if it were.
My boost gage consistently hit 11.5psi in second and third. I'm assuming that it's about .5 psi low. It seems to be a bit below 0 when the car is off. The distance it goes below zero, is also about the same distance it's off from 12 psi. It's hard to see it in first, since I have to pay attention to too many things at once...max_boost said:I'd tend to agree with your friend because the supercharger is definently louder in second gear than it is in first.
that's what i've done, and it's smooth as can be now, also "feels" more torquey than with the K&N on...goofyguy said:my solution worked 100% I put the air box back to stock. I had the Barrys intake for quite a while now. Last week I was fed up with the car acting differnt day to day. I put the air box back together and its smooth as silk again. Before it would lag bad in every shift when it was cold and still the first few when it was hot.
I, too, believe this is more or less the case. The car runs much too rich at low rpm. When shifting between 1st and 2nd gear, the rpm drops rapidly and the extra fuel causes the engine to bog down and stumble. I noticed this after I had the latest reflash update. Then, after I installed the K & N CAI, I'd get a CEL from the car running too lean. This actually seemed to be the cure for the problem. The 1 - 2 stumble was completely gone. There were no more hesitations of any kind. Shifts were totally smooth in every gear every time. But I was worried about what the lean mixture would do in the upper rpm range. I couldn't get the CEL to go away, so I removed the CAI. Oh, well maybe after the PSI-FI kit I'll be able to put it back on.sgoodhope said:Myself personaly i belive it has to do with the car being fuel injected. The cylenders become backed up. When your shifting the engin starts to slow down and the comp stops feeding fuel. then you hammer on it again and it takes a sec for the comp to start feeding it fuel again. Then you have the S/C pumpin air into the cylinders and it developes an influx. Your air to fuel mixture is not balanced. I could be totaly wrong but this is what i belive it to be.
