ecu problem or what?? Help

[rebuild4g63]

Hi everyone!
First of all I hate asking questions on these forums but.... I'd like to start off by stating I had this problem with my 95 gst before any mods. My car when out of gear can redline when I gas it. When I am in gear punching it , it only goes up to 4000 rpm to maybe 5000 if I am lucky. That said I put a brand new oem clutch, master cylinder, slave cylinder and new lines. My pedal has .5 inches of play wich is perfect to my knowledge. Now my new mods are 255 lph fuel pump, afpr, 750 cc injectors, rfl bov (have three others) , hallman boost controller, boost gauge, afr gauge, new fuel pump, new head and valves and 3 inch cat back exhaust. all I can think of at the moment . My question is why can't I get to redline. running 18lbs boost, and tuned down my afr to about 35psi. Stock turbo. If I turn up my fuel regulator it is way to rich. Thanks in advance!!!! P.s. I read alot before I ask. Doubt it is my speed sensor in advance.

will a 94 ecu with a piggyback laptop hookup work on my 95gst? If it does are there any advantages to this? Is it worth even having? I only have a stock ecu at the moment. Thanks

What is a piggyback laptop hookup? The 94 ecu will not work in the 95 without swapping all the pins into the 94 ecu connectors. The plugs are different. 1g's have 3 plugs and 2g's have 4.

Yeah that is what I was thinking. Thanks I don't know what it is some guy wants to trade me some stuff and I think he is trying to pull one on me. I was under the impression that piggybacks where not even programable anyways.

The guy said it is like a dsmlink
