I plan on buying one really soon. Which one and let me know about your experiences. I'm leaning towards the UMI due to the driveability they claim since thats my major issue. I'll be selling my FAST 90 if anyones interested. Thanks and make sure to vote.

Does anyone have any experience with umi. I was told alot of the lack of driveability was due to the straight bore design common with alot of the aftermarket 90's and the umi incorporated alot of features of the stock throttle body for driveability without a real loss of power. This car is a dd h/c and a couple horsepower give or take isn't a concern as much as driveability is. Thanks for the inputs and keep them coming.

i read a thread on here not to long ago and somebody swapped over to the umi and it seems to fix %90 of there driveability issues. but i have also heard the sticking issue has been resolved on the NW.

The UMI may have better drivability or may not. I have seen alot of the PTM tb's and everyone of them work perfect ( no tuning or driving issues). I vote for the PTM and my second vote would be for NW.

I would vote for the Nick Williams throttle body. We have a PTM on our car and it would not open all the way and was messing with the cruise control. We had to totally disassemble and then reassemble to get it to work right. Still considering getting a NW...

I have never had any drivability issues with the straight bore up to 100mm. I think where people run into issues is when they choose to adjust the resting angle of the blade instead of drilling a bigger hole in it to get the IAC in range. You end up making it way more sensitive that way.

I always drill the hole to get the IAC steps atleast under 100 when at hot idle. Then use the adjuster screw as a fine adjust. On some cars I even drill a second smaller hole since each drill size up makes a bigger amount of change than the last.
