boost leak test your car for starters. I had the same issue and it was due to Vac lines everywhere in the engine bay that were to large.

Are you hitting boost cut?

 

[Nick 95 6sp]

do you have a boost gauge? what boost numbers are showing when that happens?

vacuum leak or VSV's not working? similar to me before

Go to Stu's website take 30 minutes and read this http://www.97supraturbo.com/Seq FAQ/Seq FAQ.doc

Dont be intimadated by complexity, if I can understand it and anyone can

take 5 minutes and put the car into TTC, drive it again and report back, is it an auto or 6 speed? Here is how to do that

http://mkiv.supras.org.nz/articles/andy.htm

Check all hoses in the turbo system before doing the TTC. I highly doubt its a turbo failure, no smoke, no noise and still boosting, most problems are control related. Make Stu's website your friend

My guess would be in order 1) Faulty Hose 2) IACV VSV 3) EGCV VSV 3) EGBV VSV, but again most likely number 1

Cheers
