Sup guys, I dont think Ive posted here yet, but have been browsing a lot. Very knowledgable forums.
I recentley added 4.10s to my GT. And their awsome. Can feel the pick a lot.
The other night I was messing around on the highway. I hit it pulliung on the on ramp. 4th Tached out pretty quick. So I did it again to see my speed. Around 5800rpm, I was only at 105mph.
Is that right? Ive heard its usally like 110-115mph at the top of 4th with 4.10's.
If I put my Prochamber on (have it just havent had the time to put it on), then I could be picking up headers soon. As the summer goes on Im going to do drag radials, K&N FIPK, 70mm TB, and Plenum.
Theres a good chance I could have to shift into 5th which would suck. I really would dread that.
Heres where something may come into play. Maybe the Speedo is messed up around higher RPMs? I bought a used Diablo Tuner, for the stock tune I tried to recalibrate the speedo. They only had 4.09, not 4.10. I did that, but for the stock tune it didnt work.
So I did a Diablo tune, the guy before me must have deleted all the tunes except that one, which is equivalant to a 91 Tune. So i did that, changed my gears to 4.09's (It didnt have a 4.10 or 4.1 option) Do you think possibly that has something to do with it? My speedo isnt off I dont think though, because I was doing 50mph and looked at my GPS and it said 50mph.
Thanks for any help guys, much appriciated.
