Excellent numbers - I'm sure the tune was worth every penny. How's the drivability?

it’s a little guy but definitely gets the job done. Can’t wait for the weather to warm up a bit so the tires can actually start sticking a little. I couldn’t be happier. I really didn’t think it was going to make nearly 600. Very impressed.

Nice ! That vvti head makes that car a very responsive one .
Does the ECU master adjust the tune on the fly based on ethanol content just like the ProEFI ? So you can fill up 93 or E85 and not to worry about the tune. Having installed a flex fuel sensor , I figure it does ?
Jim is this still stock 92 bottom end ? with how many miles if yes ? And I might have missed it .. stock vvti cams too ? What clutch to do you have on that W55 ?

It is a stock 92 bottom end and stock 99 vvti head. Head was gone through and cleaned up and decked 0.0010. Has a TT head gasket and ARP head studs.
The ecu adjusts on the fly the fly based on ethanol content. 2 fuel maps are made (1 for 93 octane and 1 for e85) it then uses a calculation for anything in between. Larry at SP did a great job of making sure the car made power but was also safely done and driveable. It isn’t on the ragged edge. Made 589/520 on 19lbs of boost. And you can see the HP number still wanted to climb at 7k rpms. He could have put more into it but we both decided it was better to keep it at this level. Also, the e85 in Illinois, being winter blend, is only about 71% so in the summer when a good blend gets in there is should make a bit more power.
Im not going to push it too hard until I can get that trans replaced though. On a side note, I talked to Reid at SP and they have seen a few w58 Supras making over 700hp. He said the key to keeping it together is to not slam gears and side step the clutch. So I’ll do just that lol

Great to hear it's driving so smoothly for you! I'm amazed (yet not surprised) at the mileage of your motor and how well it's holding together. You may just inspire me to keep my 150k mi motor around for as long as possible.
