i had the gearing changed back to my bonnys stock #* so the computer wouldnt know the difference, as for the rest its just a simple repinning of the harness end
and presto my car boils the tires into second and almost third while never leaving the power band!!!!
series 2 boys better watch out!!

What did you end up doing about the electronically controlled line pressure?

Edit:
And also, isn't the TTC lock up pulse width modulated in the 65 and not in the 60?
I know there is a major difference between how they do lock up. How did you overcome that too or are you not worring about 4th?

Hell, if it'* "easy" to swap a 4T65-E in I'd do it. That'* a question I've always had. I knew the wiring would be one issue. But I'm sure there'* a lot more.... :?

that sounds very fast i wouldnt worry about the boost #'* as long as you get the result you want. by porting the intake you open up more volume that the supercharger has to fill. the supercharger is still going to pump the same amount of air in unless you change the pulley size so that means the pressure is going to be lower.

The volume change from porting a LIM is less than 2%. At the volume per stroke of the M62, you're not going to see a boost drop from a ported LIM alone.

Downstream exhaust components will show about a 1psi drop in boost alone, and rockers or a cam another PSI.

Personally, I'd ask you.....do you trust the gauge? A small vacuum leak at the MAP sensor will cause a loss of indicated boost.

With PEMs and 1.72 roller rockers, I'm not pegging my boost gauge anymore. I'm not concerned about it.

Errr.....

i have a new auto meter gauge that i pressure checked to be acurate

as for the pulse modulate tcc the 60 is also

as for series 2 boys i have several and they are all awaiting a race to see if there is such a big difference as everyone says there is

i know they have a bigger blower but they are spinning them slower
i dont know
i like my care
i like the motor
and its fast as hell

I'm pretty modded myself, and I take down my share of S2'*, but only those less modified than me. The Series 1 has it'* advantages and disadvantages.

Maybe you should come West in July and pit yours against mine for a friendly show.
