The Hypertech inserts a "performance" program of their own design that is generally based on a stock engine (or one with a 160 degree thermostat). There is no customization of the program for other engine modifications, so it is generally considered a waste of time if you have engine mods. It does let you change fan temps and some shift parameters for an automatic, but is very limited, extremely low bang for the buck and sometimes a step backward in performance.

There are programs you can use with a laptop/PC and cable that are much better. Read up in the computer/diagnostics forum.

You can easily test the integrity of the hose section with a vacuum tester or just use your lungs.

what do you mean ? what im saying is i replaced that evap line just like one in the video with sp boot the end that goes to tb fit good but end that the back line goes into feels lil loose is this ok ? how will i tell if somethings wrong.

TGGodfrey

its not ok to be loose. If its real close you can use a zip tie as a clamp to seal it up. Otherwise find another solution.

they dont make that part anymore why they say use sp boot the tb part fits good the other fits so so i can pull it off easy ? i can try the zip. if it a lil loose what will it do ?

i used the 8mm think i should do 7mm ?

Use RTV at the loose connection. Make sure the RTV is "sensor safe".

rtv do they sell it at local parts store ? also whats a good Serpentine Belt mine looks new but sequels soooooooooooooo bad.

Put whatever laps of electrical or teflon tape needed on the EVAP solenoid port to snug it up. Removing the end at the TB and blowing into it should tell you if it is leaking. The ports should be closed from each other unless energized.

Goodyear Gatorback is a good belt.

I think the part that is loose is the way the plastic tube fits into the small (wire) end of the spark plug boot.

Yes, any auto parts store will stock various grade of RTV sealer. Ask for it.

can you send a ebay link to the Goodyear Gatorback belt that will fit my 94 z28 cant find it.

Because of a change in the size of the a/c pulley during the 1994 model year, you could have one of two different sizes of belt. One ends in 637 (shorter), the other in 642 (longer). I know Summit has the 4060642, but you may need to measure your old belt to be sure of the size. Sorry, I am not going to search the whole internet when you can do it.
